Associate Professor of Mathematics Debra Boutin presented her work "The Determining Number of a Cartesian Product" at a special session on Product Graphs at the 6th Slovenian International Conference on Graph Theory at Lake Bled, Slovenia. Boutin's recent work focuses on finding a smallest set of nodes that captures all the symmetries in a network. In this talk Boutin surveyed work in the area, gave her recent results, and suggested a new topic for research.

Associate Professor of Mathematics Debra Boutin presented her work at the 1st Canadian Discrete and Algorithmic Mathematics Conference in Banff Alberta Canada. Boutin's recent work focuses on finding a smallest set of nodes that captures all the symmetries in a network. In this talk Boutin gave upper and lower bounds on the size of such a set when the network is presented with a particular decomposition.
