The notion of contra continuous functions was introduced and investigated by Dontchev. In
this paper, we apply the notion of ω‐open sets in topological space to present and study a …

The notion of contra-continuous functions was introduced and investigated by Dontchev [5].
In this paper we apply the notion of b-open sets in topological space to present and study a …

We introduce a new notion called contra-(μ, λ)-continuous functions as functions on
generalized topological spaces [8]. We obtain some characterizations and several …

The aim of this paper is to introduce and investigate some new classes of mappings called
contra-M-continuous mappings and almost contra-M-continuous mappings via M-open sets …

Abstract In 1994, Julian Dontchev called a function f of one topological space X to another Y
to be contra continuous if, for each open subset V of Y, the inverse image f-1 [V] is a closed …

In this paper we introduce a new class of semi generalized b-continuous mapping (briefly
sgb-continuous), semi generalized b-closed (briefly sgn-closed) map and studied some of its …
