Location: Richard Berry Building - Russell Love Theatre

Abstract: Given a field k how large must the integer n be to ensure that every quadratic form over k, in more than n variables, has a non-trivial zero over k? What happens when we have r quadratic forms?

The talk will discuss these questions for fields k of arithmetic interest, particularly the p-adic fields.
