Speaker Daniel Wise (McGill) Title Counting Wcycles in Graphs, the HannaNeumann Conjecture, and the coherence of one-relator groups Date 330PM

Extractions: Abstract: I will discuss a conjecture about counting certain cycles in a labelled directed graph. If the conjecture holds then every one-relator group is "coherent" which means that all its finitely generated subgroups are finitely presented. I will describe a connection with the Hanna Neumann Conjecture, which plays a role in the proof. In particular, I obtain the following result: W^n
