Convex Analysis and Chaos : The Third Symposium on Nonlinear Analysis, July 23-25, 1998 Josai University

The homotopic invariance of fixed points of set-valued contractions and nonexpansivemappings is studied. As application, nonlinear alternative principles are given. A Leray-Schauder alternative and an antipodal theorem for set-valued nonexpansive mappings arealso included.Convex Analysis and Chaos : The Third Symposium on Nonlinear Analysis, July 23-25, 1998 Josai University, edited by Kiyoko Nishizaw
