Abstract/Media

We will give explicit constructions of hyperbolic buildings as universal covers of certain CW-complexes. The fundamental groups of these complexes still have a chance of not to be residually finite and do not contain surface subgroups. In the second half of the talk, we will explain how to show that the quadratic equations in hyperbolic groups are NP-complete.
