Abstract:In this paper new topological concepts connected with fuzzy multi-valued functions theory-as presented in the first part of this work-are introduced and their properties are investigated. As will be shown in future papers these concepts and properties are indispensable in connection with the analysis of fuzzy economic systems.
Keywords:Closed  Sequentially-bounded  Superlinear  Lower semicontinuous  Upper semi-continuous fuzzy multi-valued function
