Overview

In this talk I will give proofs of some “invariance principles” in probability; the Central Limit Theorem, the Berry–Esseen Theorem, and multidimensional and higher-degree versions thereof. I will discuss these proofs from a computer science perspective, and show some applications to fields such as property testing, derandomization, learning, and inapproximability.
