Another look at -adic Fourier-theory
Guido Kings, Johannes Sprang
In this short note, we show that a natural generalization of the -adic Fourier theory of Schneider and Teitelbaum follows immediately from the classification of -divisible gr…

-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…

Algebraicity of critical Hecke -values
Guido Kings, Johannes Sprang
In this survey, we review the known results on the algebraicity of critical values of Hecke -functions and explain the new developments in \cite{Kings-Sprang}.
