Oddness of residually reducible Galois representations

Tobias Berger

We show that suitable congruences between polarized automorphic forms over a CM field always produce elements in the Selmer group for exactly the +/--Asai (aka tensor induction) re…

On lifting and modularity of reducible residual Galois representations over imaginary quadratic fields

Tobias Berger, Krzysztof Klosin

In this paper we study deformations of mod $p$ Galois representations $τ$ (over an imaginary quadratic field $F$ ) of dimension $2$ whose semi-simplification is the direct sum of tw…

A $p$ -adic Hermitian Maass lift

Tobias Berger, Krzysztof Klosin

For $K$ an imaginary quadratic field with discriminant $- D_{K}$ and associated quadratic Galois character $χ_{K}$ , Kojima, Gritsenko and Krieg studied a Hermitian Maass lift of ellipti…
