McGill professor to speak at geometry/topology seminarTweet
There will be a topology seminar at 9:40 a.m. Friday, April 19, in LN-2201. Dani Wise, professor from McGill University, will speak about Tubular Cubular Groups. Let G split as a finite graph of free abelian groups with cyclic edge groups. We characterize when G acts freely on a CAT(0) cube complex. We show that if G acts properly and semi-simply on a CAT(0) space then G acts freely on a CAT(0) cube complex.
