  • Abstract:

    Graph coloring is a central topic in combinatorics with many applications, from maps to chemistry refrigerators. An instance of a list coloring problem inputs a graph G=(V,E) together with sets L(v) of 'colors' for each v in V. One is asked to produce a 'coloring' function S on V with the properties that S(v) is in L(v) for each v in V, and for each w adjacent to v, S(w) is not equal to S(v). In this talk I discuss an interesting family of conditions on the lists L(v) which guarantee the existence of a coloring.
