Title: Topological Combinatorics

ABSTRACT:    Topological Combinatorics is a relatively new subdiscipline of mathematics, with a history of merely three decades, where methods of  (usually equivariant) Algebraic Topology are used to prove theorems in Combinatorics.(This is in contrast to the more classical Combinatorial Topology where Combinatorics is the tool and the aim is Topology.) In many cases either no "combinatorial" proof is known, or such proofs are more complicated, less intuitive and are discretized versions of the continuous proof. Examples are the Kneser and Lovasz Conjectures (about graph colorings), the Evasiveness Conjecture (of Complexity Theory), Necklace Splittings as well as related results in finite group theory (Homological Sylow Theorems) and discrete/convex geometry (Topological Radon-Tverberg Theorems).

 

By far the most useful facts are the Borsuk-Ulam Theorem, the so called Dold's Theorem (a generalization of Borsuk-Ulam) and extensions of these. Some of these (completely topological) results were in fact motivated by such applications as mentioned above.  The talk will be mostly explaining and fleshing out this abstract with examples.
