Résumé : I will explain theory convexity for lattices, free Abelian groups without torsion. I will show that a famous class of polytopes, polymatroids of combinatorial optimization, is related to one of classes of discrete convexity. Several instances of discretely convex functions related to combinatorics of Young tableaux will be demonstrated.
