Following great progress in automorphic forms over totally real fields, there has recently been renewed interest in the case of automorphic forms over imaginary quadratic fields (aka Bianchi modular forms). One way to study their arithmetic properties is to lift them to Siegel modular forms via the theta correspondence between O(3,1) and Sp(4). This workshop brings together experts on automorphic forms, Galois representations and computational number theory to present their work on different aspects of Bianchi and Siegel modular forms. The workshop aims to inform participants of the latest developments as well as stimulate further work in this exciting area of research.

Some of the topics to be discussed at the workshop:

The event will take place in the Hicks Building at the University of Sheffield, opening on Monday morning and closing on Wednesday at 1pm. There will be a conference dinner on Tuesday.
