On the -adic Littlewood conjecture in odd characteristics

Li Lai, Johannes Sprang

The -adic Littlewood conjecture is a function field analogue of the famous -adic Littlewood conjecture in Diophantine approximation. In this paper, we prove that the $P(t)…

-adic -functions for Hecke characters of totally imaginary fields

Guido Kings, Johannes Sprang

We construct -adic -functions interpolating critical -values of algebraic Hecke characters for arbitrary unramified primes and any totally imaginary field. For non-ord…

Many -adic odd zeta values are irrational

Li Lai, Johannes Sprang

For any prime and we prove that for any sufficiently large positive odd integer at least of the -adic zeta va…

Integral p-adic cohomology theories for open and singular varieties

Veronika Ertl, Atsushi Shiho, Johannes Sprang

For open and singular varieties in positive characteristic p we study the existence of an integral p-adic cohomology theory which is finitely generated, compatible with log crystal…

Eisenstein-Kronecker classes, integrality of critical values of Hecke -functions and -adic interpolation

Guido Kings, Johannes Sprang

We show that for an arbitrary totally complex number field the (regularized) critical -values of algebraic Hecke characters of divided by certain periods are algebraic i…

A Linear independence result for -adic -values

Johannes Sprang

The aim of this paper is to provide an analogue of the Ball-Rivoal theorem for -adic -values of Dirichlet characters. More precisely, we prove for a Dirichlet character a…
