This paper deals with the relations between the polyhedron described by the inequalities of a block structured problem and the polyhedra described by the inequalities of the single blocks. In particular, classes of block structured problems are described for which zero-lifting of facet inducing inequalities of a single block yields facet inducing inequalities for the whole problem. Some applications are discussed.

Abstract
This paper deals with the relations between the polyhedron described by the inequalities of a block structured problem and the polyhedra described by the inequalities of the single blocks. In particular, classes of block structured problems are described for which zero-lifting of facet inducing inequalities of a single block yields facet inducing inequalities for the whole problem. Some applications are discussed.File in questo prodotto:
