## The Brouwer fixed point theorem

**Date:** 4:00pm - 5:00pm PST November 20, 2013

The talk is on: the Brouwer fixed point theorem

The Brouwer fixed point theorem is one of the most well-known theorems in topology, in part for the number of applications it has across various fields of mathematics, and in part because it can be proved in many ways. The theorem states that a continuous function from a ball to itself has a fixed point. In this talk I will explain the theorem with examples, present applications, and introduce some concepts in algebraic topology in order to prove it.
