چکیده

In this paper, we introduce upper and lower almost δ-M -continuous multifunctions as a generalization of δ-M -continuous multifunctions. Some characterizations and several properties concerning upper and lower almost δ-M -continuous multifunctions are obtained. The relationships between upper δ-M -continuous multifunctions and upper almost δ-M -continuous multifunctions are also discussed. Mathematics Subject Classification: 54A08, 54C60

Almost δ-Precontinuous Multifunctions

In 2001, El-Monsef and Nasef have introduced γ-continuous multifunctions and in 2004, Park, Lee and Son have studied δ-precontinuous multifunctions. The purpose of this paper is to generalize some types of continuous multifunctions. In this paper, the notion of almost δ-precontinuous multifunctions is studied. Basic properties, characterizations and relationships of almost δ-precontinuous multi...

On upper and lower α-continuous fuzzy multifunctions

In this paper a new type of fuzzy multifunction termed as δ-precontinuous fuzzy multifunction has been introduced and studied. Some characterizations and several properties of this multifunction are obtained. We also characterize this multifunction by newly define fuzzy neighbourhood of a fuzzy set in a fuzzy topological space. Finally, in the last section some applications of this fuzzy multif...

Almost δ∗ - Pre-I-Continuous Multifunctions

In this paper we introduce and investigate a new type of weaker class namely δ∗-pre-I-continuous and almost δ∗-pre-I-continuous multifunctions in ideal topological space. Some characterizations of almost δ∗ pre-I-continuous multifunctions are obtained. Mathematics Subject Classification: 54C05, 54C08

Some results on (δ-pre, s)-continuous functions

One of the important and basic topics in general topology and several branches of mathematics which have been researched by many authors is the continuity of functions. In this paper, we study (δ-pre, s)-continuous functions as a new weaker form of continuity. In 1996, Dontchev [3] introduced contra-continuous functions, and Jafari and Noiri [10] introduced contra-precontinuous functions (in 20...

On upper and lower almost weakly continuous fuzzy multifunctions

The aim of this paper is to introduce the concepts of fuzzy upper and fuzzy lower almost continuous, weakly continuous and almost weakly continuous multifunctions. Several characterizations and properties of these multifunctions along with their mutual relationships are established in $L$-fuzzy topological spaces
