Introduction to group cohomology and a fixed point theorem

Shaked Bader
(Mathematical Institute University of Oxford)
Abstract
Most of the talk would be devoted to basic definitions and cute facts that are easy to prove with group cohomology. In the second part I'll state and prove a recent fixed point theorem which is joint work with Saar Bader, Uri Bader and Roman Sauer. Both parts of the talk should be followable to anyone who knows undergraduate level Algebraic Topology.

Dehn Surgery and Knots

Misha Shmalian
((Mathematical Institute University of Oxford))
Abstract

Dehn surgery is a method of building three-dimensional manifolds that is ubiquitous throughout low-dimensional topology. I will give an introduction to Dehn surgery and discuss recent work with M. Kegel on the uniqueness of Dehn surgery descriptions of 3-manifolds. To do this, I will discuss the reason that Dehn surgery is so prominent - namely that it interacts very well with many structures, such as the geometry and gauge theory of 3-manifolds. (I will do my very best to assume very little background knowledge.)
