Title: Minimal induced subgraphs of two classes of 2-connected non-Hamiltonian graphs

Speaker: Zishen Qu Affiliation: University of Waterloo Zoom: http://matroidunion.org/?page_id=2477 or contact Shayla Redlin

Abstract:

Finding sufficient conditions for a class of graphs to be Hamiltonian is an old problem, with a wide variety of conditions such as Dirac's degree condition and Whitney's theorem on 4-connected planar triangulations. We discuss some past results on sufficient conditions for Hamiltonicity involving the exclusion of fixed induced subgraphs, and some properties of the graphs involved in such results.
