The organizers of the Algebraic Graph Theory International Webinar would like to invite you to join us and other colleagues on March 21, 2023, at 7pm Central European Summer Time (= 6pm UTC), for the next presentation delivered by Veronika Bachrata.

The title: Eigenvalue bounds for the independence and chromatic number of graph powers

Abstract:
In this talk I will present several eigenvalue bounds on the independence number and the distance chromatic number of graph powers. We will see how to use polynomials and mixed-integer linear programming in order to optimize such bounds. Some infinite families of graphs for which the new bounds are tight will also be shown.
