Rinat Kashaev (Université de Genève) — Multivariable knot polynomials from Nichols algebras
By using a specific general formula, one can associate an R-matrix over the underlying vector space of an arbitrary braided Hopf algebra H endowed with an automorphism. In the case of Nichols algebras, it leads to multivariable knot polynomials generalising those related to Borel parts of small quantum groups. This is a work in progress in collaboration with Stavros Garoufalidis.
