Combinatorial Fixed Point Theorems


Combinatorial Fixed Point Theorems
Location: Steward Observatory N210
Presenter: Francis Su, Harvey Mudd College

Sperner's Lemma is a combinatorial analog of a famous theorem in topology: the Brouwer fixed point theorem. In this talk, I will trace recent connections, generalizations, and applications of Sperner's lemma to the Nash equilibrium theorem in economics, problem of fair division, and the game of Hex.
