Arithmetic Study Group: Supersingular abelian varieties with non semisimple Tate module

Presented by Maja Volkov, Universite de Mons

23 January 2018 14:00 in CM 219

We show the existence of abelian varieties over Q_p with good supersingular reduction and non semisimple p-adic Tate module. This result is an application of the characterisation in terms of filtered phi-modules, via p-adic Hodge theory, of the p-adic representations of the absolute Galois group of Q_p coming from abelian schemes. We will show how to obtain varieties having the desired properties for the least possible dimension, namely surfaces. Our constructions easily generalise to higher dimensions.
