  3. Oct. 18, 2018Graphs and Matroids Seminar

    Title: Extending Thomassen’s Theorem to Two Faces

    Speaker: Joshua Nevin
    Affiliation: University of Waterloo
    Room:  MC 5417

    Abstract: Let G be a planar graph and let L be a list-assignment for G in which there is a precolored edge on the outer face, every other vertex on the outer face has a list of size at least 3, and every other vertex in G has a list of size at least 5.
