Title:Complete bipartite induced minors (and treewidth)

Speaker: Sepehr Hajebi
Affiliation: University of Waterloo
Location: MC 5501

Abstract:I will present a result that describes the unavoidable induced subgraphs of graphs with a large complete bipartite induced minor, and will discuss the connections and applications to bounding the treewidth in hereditary classes of graphs. If time permits, I will also sketch some proofs.

 Joint work with Maria Chudnovsky and Sophie Spirkl.
