By Bianchi modularity, we understand extensions from classical modularity over the rational field towards imaginary quadratic fields (respectively, from SL_2(Z) towards the Bianchi modular groups).
As contributions to this, we consider studies of Bianchi modular forms, attached automorphic representations and attached Galois representations, as well as relevant cohomology and attachable Abelian varieties.
The workshop is funded by a research grant of the chairman, Gabor Wiese.
