Fuzzy closed graph fuzzy multifunctions
We study certain properties of fuzzy closed valued, fuzzy compact valued and fuzzy closed graph fuzzy multifunctions defined on a fuzzy topological space. Fuzzy closed graph theorem for fuzzy multifunctions is also obtained and an application to fixed point is shown. (C) 2000 Elsevier Science B.V. All rights reserved.
