Title: The Erdős-Pósa property for A-paths

Speaker: Jim Geelen Affiliation: University of Waterloo Room:  MC 5417

Abstract:

Let A be a set of vertices in a graph G. An A-path is a path whose ends are in A. Gallai proved, for any integer k, that there are either k disjoint A-paths or there is a set of at most 2k vertices that hit all A-paths.
