Product Growth and Mixing in Finite Groups: Variations on a Theme of Gowers
László Babai
2:00pm|S-101

For a probability distribution X over a finite set, let D(X) denote the L_2-distance of X from the uniform distribution. Let X, Y be probability distributions over the finite group G and let Z be their G-convolution. Inspired by recent work of...

Applications of the Removal Lemma
10:30am|S-101

An extension of Szemeredi's Regularity Lemma for hypergraphs, was proved in 2005 by Gowers and independently by Rodl, Schacht, Skokan, and Nagle. More recently, Tao gave another proof for the lemma. A special case, the Removal Lemma is an important...

Developments in Holographic Algorithms
Jin-Yi Cai
11:15am|S-101

Valiant's theory of holographic algorithms is a new design method to produce polynomial time algorithms. Information is represented in a superposition of linear vectors in a holographic mix. This mixture creates the possibility for exponential sized...
