Oberseminar Differentialgeometrie One of the most well known open questions in geometric group

theory is the following question of Gromov: is it true, that every one-ended hyperbolic group

contains a surfaces group? Even if we restrict ourselves to groups acting

on hyperbolic buildings the answer is not known in general. We'll present some non-obvious

embeddings of surfaces groups into groups acting on buildings as well as some

negative results, leaving a possibility for counter-examples.
