We describe four theorems from Combinatorial Number Theory, and sketch their proofs (as time permits). These theorems were important to the recent extractors and Ramsey graphs obtained in [Barak-Impagliazzo-Wigderson] and [Barak-Kindler-Sudakov...

I will talk about some joint work with Yanyan Li which extended the Liouville type theorem of Caffarelli-Gidas-Spruck's on the Yamabe equation to the fully nonlinear case.

Given a polytope P with a real-valued objective function f on its vertices, we consider the problem of finding a minima of f. Arguably the simplest randomized approach is the simplex algorithm RANDOMEDGE. Sitting at a vertex of P, RANDOMEDGE chooses...

Excited random walk is a process on Z^d which behaves like a regular balanced random walk when it reaches a vertex it already visited, but when it reaches a new vertex it has a drift to the right. We shall review a number of new results about this...
