Remarks on the Vassiliev knot invariants coming from sl 2 (1997)

S.V. Chmutov, A. N. Varchenko

this paper we give a formula for the weight system of sl 2 and describe some properties of the weight system of an arbitrary simple Lie algebra. Our formula for sl 2 is recurrent with respect to the...

Verlinde Algebras and the Intersection Form on Vanishing Cycles (1996)

Varchenko, A. N., Gusein-Zade, S. M.

We prove Zuber's conjecture establishing connections of the fusion rules of the $su(N)_k$ WZW model of conformal field theory and the intersection form on vanishing cycles of the associated fusion...
