We investigate subgroups of SL (n,Z) which preserve an open nondegenerateconvex cone in real n-space and admit in that cone as fundamental domain apolyhedral cone of which some faces are allowed to lie on the boundary.Examples are arithmetic groups acting on selfdual cones, Weyl groups of certainKac-Moody algebras and do occur in algebraic geometry as the automorphismgroups of projective manifolds acting on their ample cones.

Discrete automorphism groups of convex cones of finite type
