Characterizations of Non-Seymour Graphs

Speaker: Zoltan Szigeti
Affiliation: INP Grenoble and Ensimag
Room: Mathematics and Computer Building (MC) 5136B

Abstract: 

A graph is called Seymour if for every join F there exists a complete packing of F-cuts. Bipartite graphs and series-parallel graphs are Seymour, by two results of Seymour, of course. Numerous equivalent characterizations of non-Seymour graphs will be presented, each of them of the form: by contracting some kind of subgraphs, a special K_4 or prism can be found.
