Introduction to Cobordism Theory

Ningchuan Zhang (UIUC Math)

Abstract: In this talk, I will introduce some basic notions in cobordism theory. The focus of this talk will be unoriented cobordism and Pontrjagin-Thom construction. If time permits, I will also talk about framed cobordism and its relation to stable homotopy groups of spheres.

Keisler Measures

Santiago Camacho (UIUC)

Abstract: One of the results of the Distal paper by Simon states that generically stable measures are smooth in Distal theories. We will give an introduction to Keisler measures in particular what does it mean to be smooth and what does it mean to be generically stable. We will show that in a general setting smooth measures are generically stable, thus Simon's result implies that Distal theories are those in which this notions coincide.

Smith normal forms of some combinatorial matrices

Alexander Miller   [email] (UIUC Math)

Abstract: I will write down some results and conjectures about Smith normal forms of certain combinatorial matrices over integer polynomials.
