#### Understanding Cyclicity in Spaces of Analytic Functions

###### Jeet Sampat (Washington University St. Louis)

Abstract: TBA

#### Oriented Cohomology Theories

###### Tsutomu Okano (UIUC)

Abstract: I will discuss oriented cohomology theories in both topological and algebro-geometric settings. They naturally come equipped with useful tools such as Thom isomorphisms, Chern classes and Gysin maps. I will give a sketch of the Thom-Pontrjagin construction, from which it follows that complex cobordism is the universal (complex) oriented cohomology theory.

#### Mathematics, big data, and mobility

###### Prof. Richard Sowers   [email] (UIUC Math)

Abstract: We look at some mobility data from New York city from a mathematical perspective. We use several recent techniques from big data to identify patterns. Our interests will be traffic accidents, matrix decompositions, and the topology of congestion. The goal of the talk will be to understand how mathematics can help us understand some properties of complex human behavior.
