Corey Jones, Ohio State University, Vanishing of categorical obstructions for permutation orbifolds
Modular tensor categories are rich mathematical structures. They are important in the study of 2D conformal field theory, arising as categories of modules for rational vertex operator algebras. The orbifold construction A-> A^{G} for a finite group G is a fundamental method for producing…

Jason Brown, Dalhousie University, Independence Polynomials and Their Roots
Independence polynomials are generating functions for the number of independent sets of each cardinality in a graph G. In addition to encoding useful information about the graph (such as the number of vertices, the number of edges and the independence…
