REFSREFS

REFS

Every named reference, sequence id, theorem and attribution on this tree's root pages, resolved to a canonical URL. Ids that appear only inside a lab study are resolved in that study's own pages.

  • A row is carried here only when it resolves to a URL, a DOI or an OEIS id. Nothing softer is listed.
  • Every OEIS id below is checked on both its name and its first terms. None is misattributed.
  • One id needs its provenance said out loud. A299916 is defined arithmetically and its Menger geometry lives only in a contributor comment by Albert Safstrom; Wikipedia sources the same claim to that comment and to a newspaper piece, so no peer-reviewed source states it. The geometry is nonetheless true - it is reproved cold from the Menger digit rule, see README - but it is cited as a comment, never as the sequence's definition.
  • A000351 and A000420 are the level fills of the void and of corner-and-centre; A003463 and A125833 are Verified rows of the ledger. Every row here is consumed on a page of this tree.

Read at source in arXiv:1604.01041v2: Theorems 1.1-1.2 (pp.2-3; base 10 with one excluded digit, and base q large with s <= q^(23/80) excluded digits, s <= q - q^(57/80) when consecutive); Proposition 7.1 (p.18), the Type I estimate for the SET: sum_(q < Q, (q,10)=1) abs(#{a in A : q divides a, (a,10) = 1} - kappa #A/q) <<_A #A (log X)^(-A) for Q <= X^(50/77) (log X)^(-2A-2), residue 0, all moduli coprime to 10, a log saving, and the proof (pp.26-27) is residue-uniform; Lemma 8.1 (p.25) the large sieve sum_(q <= Q) sum_((a,q)=1) F_Y(a/q) << Q^(54/77) + Q^2 Y^(-50/77); Lemma 8.2 (p.26) the l^infinity bound exp(-c log Y/log q) for q < Y^(1/3) with a factor coprime to 10; Lemma 10.3 (pp.36-37) the l^1 bounds int F_Y << Y^(-50/77) and sup_beta sum_(a < Y1) F_(Y2)(beta + a/Y3) << Y1^(27/77); Section 16 (pp.68-69) the general-base l^1 bound ((q log q + q s)/(q - s))^k, which is O(Y^(23/80+eps)) for s <= q^(23/80), and ((q log q + q - s)/(q - s))^k for consecutive excluded digits, Y^(23/80+eps) at s <= q - q^(57/80); that section is the author's own sketch, leaving the complete details to the interested reader, and it states no Type I proposition for general q, only We can use this bound in place of Lemma 10.3 and Lemma 10.4 throughout the argument with the same (or stronger) consequences. The level 50/77 is one minus the l^1 exponent 27/77, and that exponent is the Markov eigenvalue bound (10.5), lambda_(1,4) < 2.24190 < 10^(27/77) for every choice of excluded digit. A whole-text search of the 70-page source finds Mobius once, in By Mobius inversion opening the proof of Proposition 7.1 on p.26, and finds Mertens and Liouville nowhere; Sieve sections now read at source in arXiv:1604.01041v2: Section 2 (pp.3-5) the outline, the l^1 bound (2.1) sum_(a<X) abs(S_A(a/X)) << #A X^0.36, the Type II range N in [X^0.36, X^0.425] too narrow for an asymptotic, the Harman minorant, and the remark that GRH gives only S_P << X^(3/4+o(1)) pointwise; Section 6 (pp.8-17) the decomposition with cut points z_1..z_6, Buchstab to four primes, nine integrals I_1..I_9 bounded 0.02895, 0.35718, 0.01402, 0.04238, 0.05547, 0.06622, 0.21879, 0.20339, 0.00924, sum < 0.996, giving (6.17) #{p in A} >= (1+o(1)) kappa_A #A/(1000 log X) with a Mathematica file on arXiv; Section 7 (pp.17-25) Proposition 7.2 the Type II estimate for polytope-counted 1_R with a coordinate subset summing into [9/25 + eps, 17/40 - eps] or by symmetry [23/40 + eps, 16/25 - eps], Lemma 7.4 the fundamental lemma at level X^(50/77 - eps) applied for d <= X^(1 - theta_1); Section 8 (pp.25-27) the proof of 7.1 by Mobius inversion over the divisors dhttps://link.springer.com/article/10.1007/s00222-019-00865-6

The Monthly original is behind JSTOR; it is read here through Diaconis and Fulman's verbatim (H1)-(H6) restatement.

Moran 1946Additive functions of intervals and Hausdorff measure, Math. Proc. Cambridge Philos. Soc. 42(1), 15-23 - Theorem II: if E = union E_i with the E_i closed, non-overlapping and similar to E in ratios t_i, then dim_H E = p_0 with sum t_i^p_0 = 1 and 0 < H^p_0(E) < infinity. THIS IS NOT THE VARYING-RATIO CONSTRUCTION: Theorem III reuses the same ratio list t_1, ..., t_n at every level and lets only the placement vary, the level-2 maps not needing to be compositions of the level-1 maps. Level-varying ratios are the later Moran-set literature, which carried Moran's name for that case long before Rempe-Gillen and Urbanski, who only record the usage rather than coin it - their text says that when all the maps are affine similarities the system is also referred to as a Moran set construction, their bibliography sends it to Wen, Moran sets and Moran classes, Chinese Sci. Bull. 46(22), 1849-1856 (2001), and they describe that article as a survey of results known at the time; Feng, Wen and Wu had already titled the objects homogeneous Moran sets in 1997. Cambridge Core serves bibliography and a first-page extract only; the theorem statements are read through the verbatim restatement in Fernandez-Martinez, Guirao and Rodriguez-Bermudez, which follows Moran's own notationhttps://doi.org/10.1017/S0305004100022684
Feng, Wen and Wu 1997Some dimensional results for homogeneous Moran sets, Science in China Ser. A 40(5), 475-482 - the homogeneous Moran class M(I_0, {n_k}, {c_k}) is the level-varying construction on the line with n_k pieces and one common ratio c_k at level k, which is a word's shape. Theorem 2.1 gives the Hausdorff dimension of an individual set outright: writing the class in the digit notation of the citing papers, N_j subdivisions of which K_j are kept, the evenly gapped homogeneous member has dim_H = s_1 = liminf_j log(K_1...K_j) / log(N_1...N_j) and the packed-to-one-end partial homogeneous member has dim_H = s_2 = liminf_j log(K_1...K_j) / (log(N_1...N_j) + log(N_{j+1}/K_{j+1})), and Lemma 2.2 bounds every other member by s_2 <= dim_H E <= s_1. So both an individual-set formula and the range over the class are proved, and the clean ratio sum log n_i / sum log(1/c_i), read as a liminf, is the Hausdorff dimension of the homogeneous member sitting at the TOP of that range, not a box-dimension expression above it. Theorem 2.1 and Lemma 2.2 are carried from the verbatim restatement in Lai, Perfect fractal sets with zero Fourier dimension and arbitrarily long arithmetic progressions, arXiv:1606.06684. The article is unreachable - Springer is paywalled and the publisher's own PDF mirror is over its bandwidth limit - so the volume, issue and pages are checked at Crossref and in two independent reference lists, and the content is catalogued from restatementshttps://doi.org/10.1007/BF02896955
Mauldin and Williams 1988Hausdorff dimension in graph directed constructions, Trans. Amer. Math. Soc. 309(2), 811-829 - construction matrix A = [t_{i,j}] from the edge ratios, A_beta = [t_{i,j}^beta], and Phi(beta) its spectral radius. Theorem 3: for G strongly connected the construction object has dim_H K = alpha where Phi(alpha) = 1, with 0 < H^alpha(K) < infinity. Theorem 4: in general alpha = max{alpha_H} over the strongly connected components, H^alpha(K) is sigma-finite, and is finite exactly when the components attaining alpha are pairwise incomparable. A cycle is defined there and is always a strongly connected component, which is the graph-directed reading of a periodic word; the collapse to one composite tile is a consequence of Theorem 3 and is not stated in the paper, and the setup carries one similarity per ordered vertex pair, so several children per level need duplicated verticeshttps://doi.org/10.2307/2000940

Definition 5 sets the lower and upper pressure as the liminf and the limsup of (1/n) log Z_n separately, Definition 7 takes the Bowen parameter B from the lower one, and Theorem 1.1 gives Bowen's formula HD(J(Phi)) = B(Phi) under sub-exponential growth of the alphabethttps://arxiv.org/abs/1210.7469
Cristea and Steinsky 2010Connected generalised Sierpinski carpets, Topology and its Applications 157(7), 1157-1162 - a generalised Sierpinski carpet is a plane set defined by a sequence of patterns, an m_k x m_k pattern at step k, with distinct patterns and distinct m_k allowed at distinct steps, so the family is level-varying by construction; the paper gives necessary and sufficient conditions for such a carpet to be connected in the Euclidean topology, by graph-theoretical arguments on the cutting types of the patterns. The publisher text is blocked to fetchers, so the definition, the statement and the method are read in the authors' own companion paper on totally disconnected generalised carpets, arXiv:1303.4883https://doi.org/10.1016/j.topol.2010.02.005

THE DIMENSION THEORY IS NOT IN THIS PAPER: it proves existence, uniqueness and approximation under average contractivity, and Remark 9.2 announces the dimension computation as forthcoming, associating a V x V matrix to each state and using Furstenberg-Kesten theory for products of random matrices; the computation is carried out in the companion V-variable fractals: dimension results, Forum Math. 24(3), 445-470https://arxiv.org/abs/0802.0064
Barnsley, Hutchinson and Stenflo 2012V-variable fractals: dimension results, Forum Mathematicum 24(3), 445-470, doi:10.1515/form.2011.075 - the companion that carries the dimension theory the 2008 paper only announces: it computes the almost sure Hausdorff dimension of V-variable fractals satisfying the uniform open set condition, the tools being the notion of a neck, which gives spatial homogeneity at various levels of magnification, and a variant of the Furstenberg-Kesten theorem for products of random V x V matrices. The families interpolate between the random homogeneous fractals at V = 1, which is the randomised-schedule reading inherited from the 2008 paper, and the random recursive fractals as V -> infinity.

Theorem 2.5: every linearly recurrent symbolic dynamical system is uniquely ergodic. Theorem 3.10: the cone lim M_0 M_1 ... M_n R_+^d is the convex hull of the letter-frequency vectors of the words in the system, so frequencies come from the infinite matrix product.

Corollary 2.2 gives upper-box F_C = max{upper-box F_empty, upper-box C} under the strong open set condition; Theorems 2.7 and 2.8 bound the lower box dimension and show it does not follow that pattern, behaving far more strangely than the upper box, Hausdorff and packing dimensionshttps://arxiv.org/abs/1301.1881

Theorem 3: for d >= 2 and any d-automatic sequence (u_n) with values in C, the series sum u_n (n+1)^(-s) and sum u_n n^(-s) are first components of Dirichlet vectors obeying an infinite functional equation got by splitting n on its last base-d digit, and both continue meromorphically to the whole complex plane with poles, if any, on a finite number of left semi-lattices; the proof places them at s = log(lambda)/log d + 2 i k pi / log d - l + 1 for lambda an eigenvalue of A = d^(-1)(A_0 + ... + A_(d-1)), k in Z, l in N.

Theorem 2.3, credited to Allouche, runs it backwards: (mu(n)) is not k-automatic for any k >= 2, because 1/zeta(s) has asymp T log T poles up to height T and those cannot sit on finitely many left semi-lattices.

It says plainly that proving a candidate is a genuine pole might turn out to be complicated, that under primitivity of the sum matrix with non-negative terms only log(rho)/log b is known to be a simple pole, and it leaves characterising the other poles as an open problemhttps://arxiv.org/abs/2401.13524
Burnol 2026On the analytic continuation of Dirichlet series with missing digits, arXiv:2602.19727v2 - the object itself: K(s) = sum' n^(-s) over the integers whose base-b digits all lie in A, with N = card A and A not equal to {0}. Abscissa s_0 = log_b N. Proposition 4.1: K continues meromorphically to C, obeys (1 - N b^(-s)) K(s) = sum_(a in A minus {0}) a^(-s) + sum_(m >= 1) (-1)^m ((s)_m / m!) b^(-s-m) gamma_m K(s+m) with gamma_m = sum_(a in A) a^m, has a simple pole at s_0 of positive residue, and has only simple poles, all among s_(m,k) = s_0 - m + 2 k pi i / log b, while prod_(m >= 0) (1 - N b^(-s-m)) K(s) is entire. Proposition 7.1: a vanishing residue at s_(0,k) forces vanishing at every s_(m,k). Theorem 7.4: the exponential generating function of the normalised real-axis residues is the multiplicative INVERSE of the moment generating function of the natural measure on the matching Cantor set, so those residues generalise the Bernoulli numbers. The continuation itself is credited to Allouche, Mendes France and Peyriere. No Mobius or Mertens sum appears anywhere in it. Proposition 5.1: the off-real residue lambda_(0,k) equals (log b)^(-1) times the limit over l of the sum of n^(-s_(0,k)) over admissible n of length l; Proposition 7.3: mu_(m,k) = (mu_(0,k)/mu_(0,0)) mu_(m,0), so for 1 < N < b a pole at s_(m,k) exists iff both s_(m,0) and s_(0,k) are poles; the introduction states the off-real residues are given as a limit and not studied further, and no numerical residue is printedhttps://arxiv.org/abs/2602.19727

Soc. 109(1), e12837, doi:10.1112/jlms.12837, read at source in arXiv:2108.09212v2 - Bombieri-Vinogradov type theorems for Lambda(n) 1_A(n) over the base-b set A missing one digit, b large; each saves an arbitrary power of log X against the trivial size X^zeta with zeta = log(b-1)/log b. THE THREE LEVELS ARE NOT INTERCHANGEABLE. Theorem 1 sums max_((c,d)=1) abs(E(X; d, c)) over d <= D and reaches only D = X^(1/3 - delta); Theorem 2 splits the modulus as d_1 d_2 with D_1 = X^(1/3 - delta) and D_2 = X^(1/9), so X^(4/9 - delta) in the product, at fixed c with no max; Theorem 3 is the only one reaching D = X^(1/2 - delta) and it is WEIGHTED, summing xi(d) E(X; d, c) against a well-factorable xi of level D, with no absolute value inside and no max over c. The near-1/2 level is the well-factorable one and is never an unweighted Bombieri-Vinogradov level. The method is the circle method on the Fourier structure of the missing-digit set together with exponential sums over primes in progressions; with the semi-linear sieve it gives upper and lower bounds of the right order for primes p = 1 + m^2 + n^2 missing a digit in a large odd base. Read at source: Theorems 1-3 (pp.3-4) with the definition of E(X; d, c; b, r) (the last digit r fixed, (r,b) = 1; b of order 10^632 at delta = 1/100 by the paper's own remark); the set-up (pp.7-9), Theorem 7 (pp.40-41) and the proofs of Theorems 1-3 (pp.41-43); Lemmas 9.1-9.4 (pp.45-46), the l^1, large-sieve, hybrid and l^infinity bounds of the digit transform carried from Maynard's Primes and polynomials with restricted digits. The set enters the proof only through those four norms; every modulus is carried by Lambda (Bombieri-Vinogradov in condition (b), exponential sums over primes in progressions in condition (c)); no distribution of 1_A in progressions is used or proved, the only set-level fact being the last-digit identity sum_(n < X, n = r mod b) 1_A(n) = X^zeta/(b-1) for r not congruent to a_0.

The ternary additive problem is settled on a missing-digit set; the binary one is not. The controlled norm is the l^1 of the digit transform: the circle integral of abs(sum_(n < g^k) 1_(n in S_b)(n) e(n theta)) is <<_eps g^(eps k) with eps -> 0 as g -> infinity, far past the g^(k/2) a square-root heuristic gives, and Lemma 3.2 bounds the same integral for a product measure over digit blocks by (C log g)^k. The prime side is a grand zero-density input rather than a level of distribution: the main term swings by a power of N across dyadic ranges, so no Fourier transference absorbs it.

The paper prints 1/4 + a >= (8a - 7a^2)/(4 - 2a) on that range with equality only at a = 1/2, so the new exponent is never worse and is better inside.

Balkanica (N.S.) 19, Fasc. 3-4, 349-366, read at source at p.350: In Kuipers and Niederreiter [13, theorem 2.5] it is shown that for an arbitrary net xi_N = {x_0, ..., x_(N-1)} of N >= 1 points in [0,1) the inequality D(xi_N) <= 6/(m+1) + (4/pi) sum_(k=1)^(m-1) (1/k - 1/m) abs((1/N) sum_(j=0)^(N-1) exp(2 pi i k x_j)) holds for each integer m >= 1. THE PRINTED WEIGHT IS 1/k - 1/m OVER k <= m - 1, NOT 1/k OVER k <= m; since 1/k - 1/m <= 1/k the looser form is implied and not equal.

Theorem 2.1, p.828, verbatim: Given delta > 0, there is delta' > 0 such that if theta in F_p^* is of multiplicative order t and t >= t_1 > p^delta, then max_(a in F_p^*) abs(sum_(s=1)^(t_1) e_p(a theta^s)) < t_1 p^(-delta'). So p IS PRIME, the saving is N p^(-delta) and NOT N^(1-delta), the summation length runs p^delta < t_1 <= t = ord_p(theta) with the lower bound strict, the coefficient condition is a invertible mod p, and delta' depends on delta alone. Theorem 3.1, p.829, is the same saving against the von Mangoldt weight: max_(a in F_p^*) abs(sum_(n=1)^N Lambda(n) e_p(a theta^n)) < N p^(-delta') for t > p^delta and N > t^(2+delta).

THE 2/3 EXPONENT IS NOT IWANIEC'S: it belongs to that same paper's own Theorem 3.2, there is a constant A > 0 such that if theta = A/((log q)^(2/3) (log log q)^(1/3)), then there exists at most one primitive character chi modulo q such that L(s, chi) has a zero in the region {s in C : sigma > 1 - theta, abs(t) <= q^C}, which improves Iwaniec.

Montgomery and Vaughan 2007Multiplicative Number Theory I: Classical Theory, Cambridge Studies in Advanced Mathematics 97, ISBN 978-0-521-84903-6, read at source - the numbering the classical Mobius inputs actually carry. Throughout, tau = abs(t) + 4. Theorem 6.6, p.172: There is an absolute constant c > 0 such that zeta(s) != 0 for sigma >= 1 - c/log tau, the de la Vallee Poussin region. Theorem 6.7 is NOT that region but the zeta'/zeta << log tau bound inside it, and Theorem 6.9 is the quantitative prime number theorem psi(x) = x + O(x exp(-c sqrt(log x))). THE TWO MOBIUS BOUNDS ARE NOT A NUMBERED THEOREM: they are equations (6.17) and (6.18), p.182, printed as prose after the proof of Theorem 6.9 under the words it may be shown that - M(x) = sum_(n <= x) mu(n) << x exp(-c sqrt(log x)) for x >= 2, and sum_(n <= x) mu(n)/n << exp(-c sqrt(log x)), since 1/(s zeta(s+1)) is analytic at s = 0, whence sum_(n=1)^infinity mu(n)/n = 0. Exercise 17 of Section 6.2 carries the coprime version UNIFORMLY IN THE MODULUS: if q <= x then (a) sum_(n <= x, (n,q) = 1) mu(n)/n << exp(-c sqrt(log x)) and (b) sum_(n <= x, (n,q) = 1) mu(n) log(n)/n = -q/phi(q) + O(exp(-c sqrt(log x))), both by elementary reasoning from (6.18). Theorem 11.3, p.360: There is an absolute constant c > 0 such that if chi is a Dirichlet character modulo q, then the region R_q = {s : sigma > 1 - c/log q tau} contains no zero of L(s, chi) unless chi is a quadratic character, in which case L(s, chi) has at most one, necessarily real, zero beta < 1 in R_q; such a zero is called exceptional. Corollary 11.8, p.368, is Landau's: prod_chi L(s, chi) has at most one zero in the region sigma > 1 - c/log q tau, the product over all characters mod q, the zero necessarily real and its character quadratic. Corollary 11.10 is Page's, the same conclusion for prod_(q <= Q) prod*_chi L(s, chi) in sigma >= 1 - c/log Q tau with an ABSOLUTE constant, which is stronger than a c(Q). Corollary 11.19 is the Siegel-Walfisz theorem, for psi(x; q, a) at q <= (log x)^A. THE MOBIUS FORM IS AN EXERCISE, NOT A COROLLARY: Exercise 8 of Section 11.3, p.384, Let c_1 be the constant in Theorem 11.16, and suppose that A is given, A > 0. Show that if q <= (log x)^A and chi is a character modulo q, then ... M(x, chi) <<_A x exp(-c_1 sqrt(log x)), with M(x, chi) = sum_(n <= x) chi(n) mu(n) defined at (11.39), p.383, alongside the Liouville companion Lambda(x, chi) = sum_(n <= x) chi(n) lambda(n). THE SAVING IS EXPONENTIAL, exp(-c_1 sqrt(log x)), not the (log y)^(-A) shape usually quoted. Nothing in the book states the fixed-modulus fact, that a finite family of real characters of conductor dividing a fixed Q has a genuinely zero-free sigma > 1 - c(Q)/log tau, as a numbered result; Corollary 11.10 is the printed statement nearest to ithttps://www.cambridge.org/core/books/multiplicative-number-theory-i/4E45519B26115AEEA4839C6C38206ACD

IMRN 2022(14), 10626-10648, doi:10.1093/imrn/rnab002, read at source in the published text; the arXiv copy is the 2015 first version, arXiv:1510.07711. No Type I or Type II estimate is in it: the strings Type I and Type II name no result, Vaughan and Vinogradov name no lemma, and the introduction says plainly Somewhat surprisingly, the Fourier structure is sufficient to deduce the existence of primes in A using only existing exponential sum estimates for the primes, and without having to investigate further bilinear sums. Type I-II sums appear twice, as prospects only, it appears that the method of bilinear sums, Harman's sieve and zero density estimates all have the potential to show the existence of primes missing digits when the base is noticeably smaller and one would hope that utilizing Type I-II sums and Harman's sieve would extend this to sets of smaller density. Theorem 1.1, p.2: Let q > 2000000, a_0 in {0, ..., q-1} and A = {sum_(i >= 0) n_i q^i : n_i in {0, ..., q-1} minus {a_0}}, then for any A > 0, sum_(n < q^k) Lambda(n) 1_A(n) = kappa_q(a_0) (q-1)^k + O_A((q-1)^k (log q^k)^(-A)) with kappa_q(a_0) = q/(q-1) if (a_0, q) != 1 and q(phi(q)-1)/((q-1)phi(q)) if (a_0, q) = 1; the remark adds a more involved calculation shows that q > 2500 is sufficient by the same method and one might conjecture that the result would remain true for all q > 2. Theorem 1.2 needs q > exp(exp(2r)) for a degree-r polynomial. Theorem 1.3 takes 0 < s < q^(1/5-eps) excluded digits, or q - s >= q^(4/5+eps) when they are consecutive, and the 4/5 is the paper's own limit: the exponent 4/5 is ultimately related to the 4/5 exponent of Lemma 4.2 for an exponential sum over primes and represents a limit of our basic method. Lemma 4.2, p.7, is that whole prime input: for alpha = a/d + beta with (a,d) = 1 and abs(beta) < 1/d^2, sum_(n < x) Lambda(n) e(n alpha) << (x^(4/5) + x^(1/2) abs(d beta)^(-1/2) + x abs(d beta)^(1/2)) (log x)^4. The digit set enters only through Section 5's four Fourier norms, Lemma 5.1 the l^1 bound sup_theta sum_(0 <= a < q^k) abs(F_(q^k)(theta + a/q^k)) << (C_q q log q)^k with C_q in [1/log q, 1 + 3/log q], Lemma 5.2 the large sieve, Lemma 5.3 the hybrid bound, complete at source: Let B, D >> 1. Then sum_(d ~ D) sum_((l,d)=1) sum_(abs(eta) < B, q^k l/d + eta in Z) abs(hat F_(q^k)(l/d + eta/q^k)) << (q-1)^k (D^2 B)^(alpha_q) + D^2 B (C_q log q)^k, alpha_q = log(C_q (q/(q-1)) log q)/log q, WITH NO COPRIMALITY CONDITION (d,q) = 1 AND NO RANGE ON D BEYOND D >> 1; and Lemma 5.4 the l^infinity bound (q-1)^k exp(-c_q k/log d) at d < q^(k/3), d = d_1 d_2, (d_1,q) = 1, d_1 != 1, abs(eps) < 1/(2 q^(2k/3)), (l,d) = 1, for some constant c_q > 0 depending only on q - NO SIZE FOR c_q IS GIVEN, and the proof runs on abs(e(n theta) + e((n+1) theta))^2 = 2 + 2 cos(2 pi theta) < 4 exp(-2 norm(theta)^2), so it consumes two consecutive allowed digits. Section 9, p.17, is the multi-digit extension and is a sketch by its own words, leaving the precise details to the interested reader: C_(q,s) = 1 + (2+s)/log q in general and 2 + 2/log q when the excluded digits are consecutive, alpha_(q,s) = log(C_(q,s) (q/(q-s)) log q)/log q, Lemma 5.2 remains unchanged whilst in Lemma 5.3 all occurrances of q - 1 should be replaced by q - s, and then Lemmas 5.4, 6.1, 6.2, 7.1, 7.2, 7.3 all go through as before, with alpha_(q,s) <= log s/log q + eps at s < q/2 and alpha_(q,s) <= log(q/(q-s))/log q + eps when consecutive. The paper also records that since these estimates are only used when the modulus is highly composite, in fact Siegel zeros do not play a role, and so the error terms could be replaced by effective ones of size O((q-1)^k exp(-c k^(1/2))). No Mobius or Mertens sum appears in ithttps://doi.org/10.1093/imrn/rnab002

Equation (2.15) is the two-scale relation phi(x) = sum_(n=0)^N c_n phi(2x - n) with supp phi in [0, N]; the remark after (4.29) states that a C^k solution with that support forces k <= N - 2, so regularity is bought only by widening the mask past one residue boxhttps://doi.org/10.1002/cpa.3160410705

Gauss circle survey 2023Around the Gauss circle problem: Hardy's conjecture and the distribution of lattice points near circles, arXiv:2305.03549. States the normalisation N(R) = pi R^2 + Delta(R) in the radius, Hardy's conjecture Delta(R) = O(R^(1/2 + o(1))) and Hardy's 1916 lower bound Delta(R) != O(R^(1/2) (log R)^(1/4)); it attributes the best upper bound to Bourgain and Watt, which the withdrawal above supersedeshttps://arxiv.org/abs/2305.03549
Van Loan and Pitsianis 1993Approximation with Kronecker products, in Linear Algebra for Large Scale and Real-Time Applications, NATO ASI Series 232, Springer. The nearest Kronecker product min norm(A - B (x) C)_F is the rank-one SVD of a rearrangement R(A) whose rows are the vectorised blocks, R(B (x) C) = vec(B) vec(C)^T, so the singular values of R(A) are the data's Kronecker spectrum. The chapter is paywalled: the operator and the theorem are read in the verbatim restatement of KoPA: Automated Kronecker Product Approximation, arXiv:1912.02392, which defines R and attributes the SVD connection to this chapterhttps://doi.org/10.1007/978-94-015-8196-7_17
Cawley and Mauldin 1992Multifractal decompositions of Moran fractals, Adv. Math. 92, 196-236. For a self-similar measure under the open set condition, beta(q) is defined by sum_i p_i^q r_i^(beta(q)) = 1 and the multifractal spectrum is its Legendre transform, f_mu(alpha) = beta*(alpha) for all alpha >= 0, phi*(x) = inf_y (x y + phi(y)).

Karwatowski, base 9Digits of primes in base b = 9, 17 pages, preprint on the author's page at the Mathematical Institute of Heinrich Heine University Duesseldorf, undated in the text, read at source: Theorem 1 (p.3) #{p in A(X)} asymp #A(X)/log X = X^(log 8/log 9)/log X for base 9 and excluded digit a_0 in {0, 8}; the constants (p.5) lambda(1,4) <= 9^0.3219 replacing 27/77 and 50/77 by 0.3219 and 0.6781, lambda(3/2, 4) <= 9^0.14355 replacing 235/154 and 59/433 by 3/2 and 0.14355, v = 0.28711 replacing 23/80 (p.7), all by a Mathematica code handed out on request; Section 6 (p.16) the criterion for a pair (b, a_0): g(s) < (1/5)(1 + c/2)(2 - s) for some s in [3/2, 2), g(s) = log lambda(s,J)/log b, c = log(b-1)/log b, met for (9,0) and (9,8) with a margin 7.53 x 10^(-3), and verbatim For all other pairs (b,a_0) != (9,0) and (b,a_0) != (9,8), the above condition can't be fulfilled. Mainly because c = log(b-1)/log b decreases more strongly than g(s) does, if b decreases. Thus, a refinement of Maynard's estimates in [2] or a completely new approach is necessary to make progress for bases b <= 9; the introduction records that the previous article closes every base b >= 10; the dissertation Primzahlen mit einer ausgeschlossenen Ziffer is its reference [1]; the only source is this PDF on the author's university page, no DOI and no arXiv idhttps://www.math.hhu.de/fileadmin/redaktion/Fakultaeten/Mathematisch-Naturwissenschaftliche_Fakultaet/Mathematik/20_Institut-Lehrstuehle/5_Algebra_und_Zahlentheorie/Karwatowski/Digits_of_primes_in_base_b_9.pdf

PRIOR ART ON THE BASE-3 SLICE

The upstream that spectra reads its base-3 rung against. It is grey literature: a photograph, a video, three blog posts and an OEIS comment, with two peer-reviewed generalisations that move along dimension or change the solid, never along base.

UNRESOLVED

Named on a page of this tree, with no citable source behind the name.

  • Lorenz and Hardy, named in bases for the lattice-sum identity behind 4*zeta(s)*beta(s). The identity is normally traced to Lorenz 1871 and Hardy 1920 without a standard reference; the Wikipedia row above carries Jacobi's r_2(n) = 4*(d_1(n) - d_3(n)), of which the factorisation is the immediate Dirichlet transform.
  • Dirichlet and Mertens, named in pi for the 6/pi^2 coprimality density - classical, with no paper named in this tree.
  • The Chebyshev psi asymptotic, named in coprime - classical, with no paper named in this tree.
  • The Einstein relation d_s = 2*d_f/d_w, imported in walks - named but uncited, and the page already says it is a definition outside the classical cases.
  • The accepted carpet numerics d_w ~ 2.10 and d_s ~ 1.80 in walks - attributed to stated literature values with no paper. Barlow and Bass 1999 is the rigorous foundation but does not itself state those decimals. This is the one unresolved name under a load-bearing claim.
  • Zucker 1974 is cited in bases without a title. The row above is the paper that matches the parity-restricted lattice-sum claim, and the match is inferred, not stated on the page.
  • Glaisher 1899's HathiTrust scan sits behind an automated challenge that blocks every automated check. The identical bibliographic record and the attribution both appear on OEIS A001316, which is the independent confirmation.
  • blog.zacharyabel.com serves https under a *.scripts.mit.edu certificate and 503s intermittently over http, so both Abel rows can need a web archive snapshot.
  • Three rows on the magic page have no open full text. Feng, Wen and Wu 1997 is the one with no reachable copy at all, so its theorem statements are carried from restatements; Moran 1946 gives bibliography and a first-page extract on Cambridge Core, and Cristea and Steinsky 2010 is read through its authors' own companion paper. Each row says so in place.
  • A398348's own crossrefs, and the extension credits on A396934, are the OEIS's own attributions, read on the live entries.
