This page hosts information on Carsten Schultz's talk "What is … Morse Theory?" at the "What is …?" seminar. The talk will take place on Friday, November 13, 4pm at FU Arnimallee 6, SR 031.
A Morse function on a differentiable manifold is a real valued function with only nice critical points. The idea behind Morse Theory is to use a function like this to obtain global information on the manifold. We will have a look at some instances of this approach.
