초록

In this paper, we introduce the concept of fuzzy $(\alpha, \beta, \theta, \delta, I)$-continuous multifunctions. There is a unification of several characterizations and properties of some types of modifications of upper and lower semi-continuous multifunctions. We deduce a generalized form of upper and lower continuous multifunctions, namely upper and lower $\eta \eta^{*}$-continuous multifunctions.

Abstract

There is a unification of several characterizations and properties of some types of modifications of upper and lower semi-continuous multifunctions. We deduce a generalized form of upper and lower continuous multifunctions, namely upper and lower $\eta \eta^{*}$-continuous multifunctions.
