Abstract
We develop the deformation theory of hyperbolic cone-3-manifolds with cone-angles less than , i.e. contained in the interval . In the present paper we focus on deformations keeping the topological type of the cone-manifold fixed. We prove local rigidity for such structures. This gives a positive answer to a question of A. Casson.
