Lecture 22: Structure of Set Addition II: Groups of Bounded Exponent and Modeling Lemma

Description: Continuing the discussion of Freiman’s theorem, Professor Zhao explains the Ruzsa covering lemma and uses it to prove Freiman’s theorem in groups of bounded exponent. He then explains Freiman homomorphisms, which are maps that partially preserve additive structure, as well as the modeling lemma.
