Title: Constructing Graphs Pseudo-Similar VerticesSpeaker: Cathy Wang Affiliation: University of Waterloo Room: MC 6486
Let G be a graph. Let a and b be vertices in G, then a and b are pseudo-similar if G\a is isomorphic to G\b, but there's no automorphism of G that maps a onto b.
Title: An introduction to vertex minorsSpeaker: Jim Geelen Affiliation: University of Waterloo Room: MC 5479
This introductory lecture on vertex minors of graphs will highlight the similarities and differences with minors of graphs. We will also discuss the main conjectures relating to vertex minors.
