If you have a question about this talk, please contact Guillem Perarnau. A class F of graphs has the vertex/edge-Erdös-Posa property if there is a function f:N->N such that for every natural number k and every graph G either G contains k vertex/edge-disjoint subgraphs isomorphic to a member of F or a set X of at most f(k) vertices/edges such that G-X contains no member of F as subgraph. Erdös and Posa proved in 1965 that cycles have this property and in the past 50 years many other classes were shown to have the vertex-Erdös-Posa property. However, only few classes were investigated regarding the edge-version of the property and it has been an open problem whether the vertex property implies the edge property or vice versa. I will present some recent developments in this area. Some parts of my work is joint with Felix Joos and Henning Bruhn.
