Euler’s Beta Function and Pentagon Relations
Rinat Kashaev



The (quantum) pentagon relations satisfied by the 6j-symbols of representation categories underlay the existing constructions in quantum topology based on combinatorics of triangulations of three-dimensional pseudo manifolds. We discuss the recent result as reported by Kashaev et al. (2012) on an integral five-term relation satisfied by Euler’s beta function.
