Title: The Ornstein-Weiss Quasitiling Theorem

Abstract: The Ornstein-Weiss Quasitiling Theorem roughly states that approximately invariant finite subsets of a group can almost be tiled by translates of finitely many subsets of the group with nice invariance properties. I will discuss the ideas behind this theorem and give a proof for it.
