Group Actions on CAT(0) spaces
by
Ross Geoghegan
SUNY Binghamton

I will talk about new invariants of group actions on CAT(0) spaces. They generalize the Bieri-Neumann-Strebel-Renz ßigma" invariants of a group, but they can be understood without prior knowledge of that work. This is a new part of my joint work with Robert Bieri.
