The idea of using topology in order to solve combinatorial problems has
been known for several decades, but only recently it started to become an
organized theory. In my talk I will introduce several classical
topological theorems such as Brouwer's fixed point theorem and Sperner's
Lemma and give the basic methods for using them in combinatorial settings.
I will also describe a new approach that may enable us to use the Borsuk
Ulam theorem in similar settings and hopefully obtain better results.
