1:00 pm in 2 Illini Hall,Friday, September 7, 2018

#### Dynamics and Rigidity 1: Introduction to Ergodic Theory

###### Venkata Sai Narayana Bavisetty

Abstract: This talk will be an introduction to Ergodic Theory with the goal being to develop the necessary background to prove and understand the ergodicity of the geodesic flow on hyperbolic manifolds.

3:00 pm in 145 Altgeld Hall,Friday, September 7, 2018

#### Building sandcastles via optimal transportation

###### Derek Kielty (Illinois Math)

Abstract: You’re given a lump of sand and a blue print for a sandcastle. While there are many ways to rearrange the individual grains of sand into your castle, you ask yourself, “What is the optimal way?” The theory of optimal transportation was developed to make these kinds of questions precise. In the process it developed connections to probability, geometry, and partial differential equations. In this talk I will give an introduction to optimal transportation and discuss applications to some geometric inequalities.

4:00 pm in 245 Altgeld Hall,Friday, September 7, 2018

#### You’ve Proven a Theorem, Now What?

###### Bruce Reznick (Mathematics)

4:00 pm in Altgeld Hall 241,Friday, September 7, 2018

#### A generalization of pair of pants decompositions

###### Jesse Huang (UIUC)

Abstract: We will talk about higher dimensional pair of pants decompositions for smooth projective hypersurfaces.

4:00 pm in 345 Altgeld Hall,Friday, September 7, 2018

#### An introduction to continuous logic

###### Erik Walsberg (UIUC)

Abstract: Continuous logic will be introduced. Basic knowledge of first order logic and ultraproducts will be assumed.
