#### Central limit theorems for supercritical branching Markov processes

###### Renming Song (UIUC Math)

Abstract: In this talk, I will give a survey of the recent results on spatial central limit theorems for a large class of supercritical branching Markov processes.

2:00 pm in 441 Altgeld Hall,Wednesday, October 15, 2014

#### Rings with Operations

###### Peter Nelson (UIUC Math)

Abstract: Often when one defines an algebraic invariant of a thing, it turns out to have a ring structure, and that's great. But by thinking a little more categorically (or algebro-geometrically), one can also realize even more structure. I'll talk about a framework for such nonsense, and give at least one example.

4:00 pm in 245 Altgeld Hall,Wednesday, October 15, 2014

#### Symplectic resolutions and Lie algebras

###### Andrei Okounkov (Columbia University)

Abstract: In geometric representation theory, one often links the properties of noncommutative algebras to the geometry of their commutative degenerations, and also often aims to make an algebra act on cohomology or K-theory of another algebraic variety. These points of view are in a certain sense dual, and my goal in these lectures will be to discuss several recent ideas and advances in this direction.

Andrei Okounkov of Columbia University will deliver the Trjitzinsky Lectures on October 14, 15, 16, 2014.
