Title: A Taste of Topological Methods in Combinatorics

Abstract: In the early 20th century, the discipline of combinatorial topology turned into the field of algebraic topology. The situation was reversed -- topological methods were used to solve a problem in combinatorics -- when Laszlo Lovasz proved the Kneser conjecture in 1978. This talk will explore several classical results using Brouwer's fixed point theorem and Borsuk-Ulam theorem. We will learn how to fairly split the rent and cut the necklace.
