Finiteness conjecture for Kauffman bracket skein modules of manifolds with boundary

Let R\mathcal{R} be a ring containing an invertible element AA, and let S(M,R)\mathcal{S}(M,\mathcal{R}) denote the Kauffman bracket skein module of a 3-manifold MM. Throughout, write S(M)=S(M,Q(A))\mathcal{S}(M)=\mathcal{S}(M,\mathbb{Q}(A)). For a compact oriented 3-manifold MM, let S(M,Q(A))\mathcal{S}(\partial M,\mathbb{Q}(A)) act on S(M)\mathcal{S}(M) by boundary gluing.

Finiteness conjecture. Let MM be a compact oriented 3-manifold. Then S(M)\mathcal{S}(M) is a finitely generated S(M,Q(A))\mathcal{S}(\partial M, \mathbb{Q}(A))-module.

The conjecture extends the known finite-dimensionality result for closed 3-manifolds to manifolds with boundary. The paper establishes it for the stated family of Seifert fibered spaces, while the general case remains open.
