On the skein module of the product of a surface and a circle (Gregor Masbaum, IMJ-PRG, CNRS)

26.09.2019 14:15

We show how to use Witten-Reshetikhin-Turaev invariants and Topological Quantum Field Theory to study skein modules of 3-manifolds. As an application, we obtain a lower bound for the dimension, over the fraction field, of the Kauffman bracket skein module of the product of a closed oriented surface and a circle.
