Almost contra $(I,J)$-continuous multifunctions

Contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions

The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.

Almost Nearly Continuous Multifunctions

Erdal Ekici has introduced and studied nearly continuous multifunctions [Acta Math. Univ. Comenianae, Vol. LXXII, 2 (2003), pp. 1–7]. The purpose of the present paper is to introduce and study upper and lower almost nearly continuous multifunctions as a weaker form of upper and lower nearly continuous multifunctions. Basic characterizations, several properties of upper and lower almost nearly c...

Contra-ω-Continuous and Almost Contra-ω-Continuous

ON FUZZY UPPER AND LOWER CONTRA-CONTINUOUS MULTIFUNCTIONS

This paper is devoted to the concepts of fuzzy upper and fuzzy lower contra-continuous multifunctions and also some characterizations of them are considered.

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
