A sufficient condition for the insertion of a contra-continuous (resp. Baire-one) function between two comparable real-valued functions is given on the topological spaces that Λ-sets are open (resp. Gδ-sets).

Our main purpose is to introduce the concepts of upper and lower almost contra- (Λ, sp)-continuous multifunctions. Moreover, several characterizations contra-(Λ, multifunctions are investigated

In this work, we introduce and study the classes of contra ΛIs-continuous, quasi-ΛIs-continuous ΛIs-irresolute functions in a topological space endowed with an ideal. We investigate relationships among these their respective characterizations. Also, analyze behavior certain notions under direct inverse images new functions.

Let Λ′ be a manifold. The goal of the present article is to extend non-Gödel vectors. We show that there exists a contra-locally continuous convex scalar. A central problem in computational graph theory is the derivation of almost stable subrings. Is it possible to extend independent manifolds?

This paper is devoted to the concepts of fuzzy upper and fuzzy lower contra-continuous, contra-irresolute and contra semi-continuous multifunctions. Several characterizations and properties of these multifunctions along with their mutual relationships are established in L-fuzzy topological spaces. Later, composition and union between these multifunctions have been studied. AMS (MOS) Subject Cla...
