Title: Sums of n squares
Speaker: Raman Parimala (Emory University, Atlanta, USA)
Date: 03 June 2024
Time: 2:30 pm
Venue: LH-1, Mathematics Department

We discuss representation of integers as a sum of $n$ squares. We explain the quaternionic composition law for sums of four squares and a proof of a theorem of Lagrange on which positive integers can be expressed as a sum of four squares. We outline general connections to the theory of quadratic forms.
