Speaker: Paul Elliott, University of Ottawa Time: Tuesday January 27, 11:00-12:00 Place: room STE5084, SITE Building, University of Ottawa Title: "Maximum Matching Graphs" Abstract: A maximum matching graph, M(G), of a graph G is a graph whose vertices are labelled by the maximum matchings of G and where two vertices are adjacent iff their corresponding maximum matchings differ in exactly one edge in G. We will explore some of the basic properties of maximum matching graphs. We will also establish some results about which graphs are not maximum matching graphs, placing special emphasis on those maximum matching graphs which are disconnected. Only a basic knowledge of graph theory is assumed.
