Combinatorics Seminar

Wednesday, November 29, 2017 at 4:15pm to 5:15pm

Room 2-135

SPEAKER:  Joshua Greene  (Boston College)

TITLE:  Coloring curves on surfaces

ABSTRACT

The curve complex of a surface is a central object in hyperbolic geometry and geometric group theory. It displays some remarkable combinatorial features, but these have been less intensively studied. In this talk, I will discuss the problem of determining and estimating the chromatic number of the curve complex and its relatives. Kneser graphs appear in a surprising way, and there are a number of attractive open problems.

The talk is targeted at combinatorialists with no prior background in topology. It is based on joint work with Jonah Gaster and Nick Vlamis.
