Abstract

This paper establishes several properties of polyhedral multifunctions with respect to: (a) Relationships between the lower semicontinuity and the pseudo-Lipschitz property, (b) Connectedness preservation, (c) Path-connectedness preservation. We make use of a theorem on the existence of Lipschitz selections of Lipschitz continuous multifunctions with nonempty closed convex values in Euclidean spaces.
