Title: Cones and symmetries of projective varieties Abstract: A smooth projective variety can be viewed as a compact manifold, but its cohomology groups have extra structure: the classes of subvarieties of a given dimension span a convex cone in the relevant (real) cohomology group. For some classes of varieties these cones are easy to compute,
