Math Prof. Paper Accepted for Publication
Danny Cryster, visiting assistant professor of mathematics, was recently accepted for publication in the Rocky Mountain Journal of Mathematics.
The title of his article, “Continuous-trace k-graph C*-algebras,” examines the characterization that is given for directed graphs that yield C*-algebras with continuous trace. This is established for row-finite graphs with no sources, first using a groupoid approach, and extended to the general case via the Drinen-Tomforde desingularization. A characterization of continuous-trace AF C*-algebras is obtained. Partial results are given to characterize higher-ran graphs that yield C*-algebras with continuous trace.
