If you have a question about this talk, please contact info@newton.ac.uk. NPC - Non-positive curvature group actions and cohomology In the 1990's Bestvina and Brady constructed groups that are FP but not finitely presented as the kernels of maps from right-angled Artin groups to Z. I generalize this construction using branched coverings. The main application is an uncountable family of groups of type FP. A corollary is that every countable group embeds in a group of type FP_2. I will explain the construction, and if time permits I will discuss the corollary and work with Ignat Soroko and Robert Kropholler on the quasi-isometry classification of the new groups.
