A version of Kirby calculus for spin and framed three-manifolds is given and is used to construct invariants of spin and framed three-manifolds in two situations. The first is ribbon V-categories which possess odd degenerate objects. This case includes the quantum group situations corresponding to t

In this paper we define a class of state-sum invariants of closed oriented piecewise linear 4-manifolds using finite groups. The definition of these state-sums follows from the general abstract construction of 4-manifold invariants using spherical 2-categories, as we defined in an earlier paper. We
