Title:           Quantum 6j-symbols and braiding

Abstract:   

I will explain certain 4-tensors appearing in studies of two-dimensional topological order from a viewpoint of subfactor theory of Jones and alpha-induction there, which is a tensor functor arising from a modular tensor category and a Frobenius algebra in it.  They are understood with quantum 6j-symbols and braiding.
