Abstract
Super-stability and strong stability are properties of a matching in the
stable matching problem with ties. In this paper, we introduce a common
generalization of super-stability and strong stability, which we call
non-uniform stability. First, we prove that we can determine the existence of a
non-uniformly stable matching in polynomial time. Next, we give a polyhedral
characterization of the set of non-uniformly stable matchings. Finally, we
prove that the set of non-uniformly stable matchings forms a distributive
lattice.
