Abstract:

We construct an invariant of framed links in a handlebody by means of the spin $j$ representation of ${U_q}(\mathfrak {s}\mathfrak {l}(2,\mathbb {C}))$. We can see this invariant is an extension of the Jones polynomial and Kauffman’s Dubrovnik polynomial. Moreover, we can obtain a linear representation of the generalized braid group associated with the Lie algebras of types $B$ and $C$ by applying the operators used in constructing an invariant to tangles in a solid torus.
