Description: Title: Ruzsa's theorem in additive combinatorics

Abstract: We show that in a finite group G of bouded torsion, any set
A \subseteq G such that |A + A| = O(|A|) generates a subgroup H of
size O(|A|). We will introduce some standard techniques in additive
combinatorics to prove this theorem.
