The Dulmage-Mendelsohn Decomposition for $b$-Matchings

Combinatorics 2016-06-28 v1

Abstract

We establish the theory of the Dulmage-Mendelsohn decomposition for bb-matchings. The original Dulmage-Mendelsohn decomposition is a classical canonical decomposition of bipartite graphs, which describes the structures of the maximum 11-matchings and the dual optimizers, i.e., the minimum vertex covers. In this paper, we develop analogical properties, and thus obtain the structure of the maximum bb-matchings and characterizes the family of bb-verifying set.
