Hypergeometric rational approximations to $ζ(4)$May 29 2019We give a new hypergeometric construction of rational approximations to $\zeta(4)$, which absorbs the earlier one from 2003 based on Bailey's ${}_9F_8$ hypergeometric integrals. With the novel ingredients we are able to get a better control of arithmetic ... More
A theorem of Bombieri-Vinogradov type with few exceptional moduliMay 29 2019If a set S of pairwise coprime moduli q, less than x^(9/40), is considered, one obtains the expected behavior for primes up to x in arithmetic progressions mod q, except for a subset of S whose cardinality is bounded by a power of log x.
On the density at integer points of a system comprising an inhomogeneous quadratic form and a linear formMay 29 2019We prove an analogue of the Oppenheim conjecture for a system comprising an inhomogeneous quadratic form and a linear form in $3$ variables using dynamics on the space of affine lattices.
On mixed joint discrete universality for a class of zeta-functions IIIMay 29 2019We present the most general at this moment results on the discrete mixed joint value-distribution and the universality property for the class of Matsumoto zeta-functions and periodic Hurwitz zeta-functions under certain linear independence condition on ...

Higher Correlations and the Alternative HypothesisMay 28 2019The Alternative Hypothesis concerns a hypothetical and unlikely picture of how zeros of the Riemann zeta function are spaced which one would like to rule out. In the Alternative Hypothesis, the renormalized distance between nontrivial zeros is supposed ... More
Interpolation over ZZ and torsion in class groupsMay 28 2019We prove an interpolation result over the integers, and use this to give a new proof that class groups of rings of integers are torsion.
Practical numbers among the binomial coefficientsMay 28 2019A "practical number" is a positive integer $n$ such that every positive integer less than $n$ can be written as a sum of distinct divisors of $n$. We prove that most of the binomial coefficients are practical numbers. Precisely, letting $f(n)$ denote ... More
On multiplicative automatic sequencesMay 28 2019We show that any automatic multiplicative sequence either coincides with a Dirichlet character or is identically zero when restricted to integers not divisible by small primes. This answers a question of Bell, Bruin and Coons. A similar result was obtained ... More
