Debra Boutin

Debra Boutin, professor of mathematics, organized a mini-symposium titled "Graph Colouring" at the Society of Industrial and Applied Mathematics Conference on Discrete Mathematics, in Denver, Colo.

In this mini-symposium, 10 invited speakers discussed recent work and progress in a variety of types of graph colorings. In her presentation "The Cost of 2-Distinguishing in Cartesian Products," Boutin surveyed some known techniques in measuring network symmetries and introduced a new method to find such measurements more precisely.
