Every Nontrivial Facet-Defining Inequality for the Corner Polyhedron is an Intersection Cut ConfortiMichele CornuejolsGerard ZambelliGiacomo 2005 Intersection cuts were introduced by Balas and the corner polyhedron by Gomory. It is a classical result that intersection cuts are valid for the corner polyhedron. In this paper we show that, conversely every nontrivial facet-defining inequality for the corner polyhedron is an intersection cut.
