Wedderburn’s Theorem and the Four-square Theorem

Speaker : Samarpita Ray

Date : 26th August, 2014 (Tuesday)

Time : 09:15 pm – 10:15 pm

Venue : Lecture Hall I, Department of Mathematics

Abstract : In this talk we shall give a sketch of the proof of Wedderburn’s Theorem which states that every finite division ring is a field. Using this theorem, we will prove that every positive integer can be expressed as the sum of squares of four integers, which is the well-known Langrange’s Four-square Theorem.
