WebTopological Fixed Point Theory of Multivalued Mappings - Lech Grniewicz 2006-06-03 This book is devoted to the topological fixed point theory of multivalued mappings including applications to differential inclusions and mathematical economy. It is the first monograph dealing with the fixed point theory of multivalued mappings in metric ANR spaces. WebA locally convex space Xis a vector space endowed with a family P of separating seminorms. Hence for every element x∈ X there is a seminorm p∈ P such that p(x) = 0. Therefore P gives Xthe structure of (Hausdorﬀ) topological vector space in which there is a local base whose members are covex. ray ban crystal green polarized lens review
