Abstract: The set of closed convex cones in $\R^d$ ($d\ge 3$), with the operations of intersection and closed sum, is a lattice. We determine all endomorphisms of this lattice. As a consequence, we obtain a characterization of the duality of convex cones.
Keywords: lattice of convex cones, lattice endomorphism, duality, order preserving mapping
