Zeros of systems of quadratic formsColloquium
Institution: University of Oxford
Date: Tue 20th March 2012
Time: 12:00 PM
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.
