Let L be a family of lattice-free polyhedra in Rm containing the splits. Given a polyhedron P in Rm + n, we characterize when a valid inequality for P ∩ (Zm × Rn) can be obtained with a finite number of disjunctive cuts corresponding to the polyhedra in L. We also characterize the lattice-free polyhedra M such that all the disjunctive cuts corresponding to M can be obtained with a finite number of disjunctive cuts corresponding to the polyhedra in L for every polyhedron P. Our results imply interesting consequences, related to split rank and to integral lattice-free polyhedra, that extend recent research findings.
