Title: Sperner’s Lemma: Old and New
Abstract: Sperner’s Lemma is perhaps best known as a combinatorial equivalent of the Brouwer fixed point theorem. In this talk, I’ll survey old and new proofs of Sperner’s lemma, and old and new applications, such as computing Nash equilibria and solving fair division problems. We’ll also discuss some surprising recent generalizations of Sperner’s lemma.
