Slava Krushkal (University of Virginia), Triangle Topology Seminar

October 2, 2017 @ 4:30 pm - 5:30 pm

Location: SAS 1102 at North Carolina State University, 4:30 pm Title: Flow and Yamada polynomials, planar triangulations, and TQFT Abstract: In the 1960s Tutte observed that the value of the chromatic polynomial of planar triangulations at (golden ratio +1) obeys a number of remarkable properties. In this talk I will explain how TQFT gives rise to a conceptual framework for studying planar triangulations. I will discuss several extensions of Tutte's results and applications to the structure of the chromatic and flow polynomials…
