3-Manifold Seminar: Colorings of graphs

Seminar | February 7 | 3:40-5 p.m. | 891 Evans Hall

 Ian Agol, UC Berkeley

 Department of Mathematics

I'll discuss the question of whether a map on a compact surface has a finite-sheeted covering which is 4 colorable? We can deduce this from a question about automorphism group-invariant probability measures on the space of c-colorings of a graph of chromatic number c. Some related results will be discussed.
