Abstract: In this article we introduce a theory of convexity for the lattices of integer points, which we call a theory of discrete convexity. In particular, we obtain generalizations of Edmonds' polymatroid intersection theorem and the Hoffman-Kruskal theorem as consequences of our constructions.

Keywords: pure systems, unimodular systems, polymatroids, dicing, laminarization

Category 1: Combinatorial Optimization (Polyhedra )
