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.
