Groups and Combinatorics Seminar, The Merino Welsh Conjecture Other events...
Abstract:

Merino and Welsh conjectured that for any loopless bridgeless graph, the number of spanning trees is dominated either by the number of acyclic orientations of the graph, or by the number of totally cyclic orientations of the graph.

In this talk, I will discuss this conjecture and the partial results that have been previously obtained, along with a proof (which is joint work with Steve Noble) that the conjecture is true for series-parallel graphs.
