Graduate Collloquium: "Geometry and the Four Color Theorem"

Speaker: Aliakbar Daemi, Washington University in Saint Louis

Abstract: Geometrical methods proved to be useful in addressing many problems in topology. One instance of such problems seems to be the four color theorem: any map of regions can be colored with four colors such that any two neighboring regions do not admit the same color. In this talk, I will explain how the four color theorem can be rephrased as a question in topology, and then discuss a program aimed at giving a computer-free proof of this famous combinatorial theorem.
