    • FACES OF MATCHING POLYHEDRA 

      Pulleyblank, William R. (University of Waterloo, 2016-09-30)
      Let G = (V, E, ~) be a finite loopless graph, let b=(bi:ieV) be a vector of positive integers. A feasible matching is a vector X = (x.: j e: E) J of nonnegative integers such that for each node i of G, the sum of ...
    • SUBMODULAR FUNCTIONS, GRAPHS AND INTEGER POLYHEDRA 

      Giles, Frederick Richard (University of Waterloo, 2016-09-12)
      This thesis is a study of the faces of certain combinatorially ­defined polyhedra. In particular, we examine the vertices and facets of these polyhedra. Chapter 2 contains the essential mathematical background in polyhedral ...
