Abstract

This paper is a continuation of [2]. In this paper a net in a topological space is used as a tool for characterizations of fuzzy upper (lower) δ-precontinuous multifunctions. Also we have established a mutual relationship between fuzzy upper (lower) semi-continuous multifunctions and fuzzy upper (lower) δ-precontinuous multifunctions.

Keywords
