4:00 pm Thursday, April 5, 2018 Colloquium: Coloring maps on surfaces
by Ian Agol

We'll discuss various questions about coloring maps on surfaces. We give a criterion for 3-coloring quadrangulations of the plane. Then we'll consider whether a finite map on a surface can admit a 4-coloring in a finite-sheeted cover.
