Zilin Jiang Carnegie Mellon University 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 BorsukUlam theorem. We will learn how to fairly split the rent and cut the necklace.
