This term's study group will be in two parts with a talk linking the two. First we will look at Bianchi modular forms, starting with an overview of the role they play in extending questions of modularity of elliptic curves from Q to imaginary quadratic fields, followed by a talk on topological aspects of Bianchi groups and one on Diophantine applications. The linking talk will be about theta functions associated to Bianchi Eisenstein series. In the second half of term we will have several talks about theta functions and their applications, including solving quintic equations (full details of topics, and speakers, to be decided).
All meetings will be at 1pm in D1.07 (Complexity Seminar Room).
