Excisive bivariant theories

David Gepner (Purdue)

Abstract: We construct stabilizations of infinity-topoi via bivariant theories which are excisive in the sense that they admit twisted Thom isomorphisms. This can be used to recover global forms of cohomology theories such as TMF and variants thereof. This is joint work with Thomas Nikolaus.

Some applications of the container method in discrete geometry

Jozsef Balogh (Department of Mathematics, University of Illinois)

Abstract: The container method proved to be applicable in several areas of combinatorics. I will discuss some new applications. 1. We consider a problem of Erdos about point sets in the plane in (almost) general position. 2. We discuss epsilon-nets, where the underlying set is a subset of points in the plane, and the ranges are collinear point tuples. Though we have not completely solved any of the problems, maybe our improvements are of some interests. It is joint work with Jozsef Solymosi.

Quantum value of classical games

Marius Junge (UIUC)

Abstract: Following Scpara and Dailleux we will prove a parallel repetition for the quantum value of free games.
