Abstract: Extremal Combinatorics studies how large or how small a collection of finite objects can be, if it has to satisfy certain restrictions. In this talk, we will discuss how eigenvalue interlacings can be used to prove various interesting results in Extremal Combinatorics, including the Erdos-Ko-Rado Theorem and its degree version, an isodiametric inequality for discrete cubes, and the resolution of the Sensitivity Conjecture.
This talk is self-contained and assumes no knowledge further than linear algebra.
