Stickelberger annihilators of logarithmic class groups

Number Theory 2020-12-04 v4

Abstract

For any odd prime number \ell and any abelian number field F containing the \ell-th roots of unity, we show that the Stickelberger ideal annihilates the imaginary component of the \ell-group of logarithmic classes and that its reflection annihilates the real componen of the Bertrandias-Payan module. As a consequence we obtain a very simple proof of annihilation results for the so-called wild {\'e}tale \ell-kernels of F .
