To construct the invariants we develop tensor product theorems for finite dimensional modules of U_q(osp(1|2n)) at roots of unity.6 pages, latex, no figures, submitted to the proceedings of the 24th International Colloqium on Group Theoretical Methods in Physics held in Paris, July 2002Quantum AlgebraGeometric Topology17B37; 57M27text
