Next week’s talk will be given by Prof. Tom Fisher on elliptic curves; details are below. We will again be meeting in the CMS rather than the Winstanley.

Title: Elliptic curves in geometry and arithmetic
Speaker: Tom Fisher
Abstract: Elliptic curves may be regarded as the first non-trivial curves, and admit a rich theory starting with the fact that they are both algebraic curves and groups. In this talk I will start by describing some classical problems in geometry and number theory, before explaining what they have to do with elliptic curves. I will also discuss what is known, and what is expected to be true, about ranks of elliptic curves over the rational numbers.
