Associate Professor of Mathematics Debra Boutin gave a talk "Thickness and Chromatic Numbers of Inflated Graphs" at the Joint Mathematics Meetings in San Francisco in January. In her talk Boutin described the current state of work she's done with Michael Albertson of Smith College and Ellen Gethner of University of Colorado, Denver, on r-inflated networks. A network is r-inflated by replacing each vertex in by a set of r mutually connected vertices and replacing each edge between a pair of vertices with all edges between the associated 2r vertices.

Associate Professor of Mathematics Debra Boutin recently published a research article "The Determining Number of a Cartesian Product" in the Journal of Graph Theory. This work continues Boutin's studies finding a smallest set of nodes that captures all the symmetries in a network. In this recent work she closely bounds the size of such a set in a large class of networks created by taking products of smaller networks.
