$(\Lambda,s)$-closed set, generalized $(\Lambda,s)$-closed set, $(\Lambda,s)$-$R_0$ space, almost $(\Lambda,s)$-continuous function


The purpose of the present article is to introduce the notion of (Λ, s)-closed sets. Especially, some properties of generalized (Λ, s)-closed sets are obtained. Several characterizations of some low separation axioms are given. Characterizations of (Λ, s)-extremally disconnected spaces are investigated. Furthermore, some characterizations of almost (Λ, s)-continuous functions are discussed.
