Vertex finiteness for relatively hyperbolic groups

By Gilbert Levitt

Given a finitely generated group G, we consider all splittings of G over subgroups in a fixed family (such as finite groups, cyclic groups, abelian groups) . We discuss whether it is the case that only finitely many vertex groups appear, up to isomorphism. (Joint work with Vincent Guirardel)
