Topological Methods in Discrete Mathematics and Computer Science

Instructor: Rado Fulek and Uli Wagner

Teaching Assistant: Sergey Avvakumov

Schedule (subject to change)

Date Topic Location Other


Starting with Lovász' solution of Kneser's conjecture in 1978, a number of problems in discrete mathematics and theoretical computer science have been solved using methods from algebraic and geometric topology. The aim of this course is to explain some of these results and methods to a broad audience; the precise choice of topics will depend on the audience's background.

Sample topics incude:


Weekly homework and final exam
