Some Results of τ1τ2-δ Semiconnectedness and Compactness in Bitopological Spaces

Abstract EN

We are going to establish some results of τ1τ2-δ semiconnectedness and compactness in a bitopological space.

Besides, we will investigate several results in τ1τ2-δ semiconnectedness for subsets in bitopological spaces.

In particular, we will discuss the relationship related to semiconnectedness between the topological spaces and bitopological space.

That is, if a bitopological space (X,τ1,τ2) is τ1τ2-δ semiconnected, then the topological spaces (X,τ1) and (X,τ2) are δ-semiconnected.

In addition, we introduce the result which states that a bitopological space (X,τ1,τ2) is τ1τ2-δ semiconnected if and only if X and ϕ are the only subsets of X which are τ1τ2-δ semiclopen sets.

Moreover, we have proved some results in compactness also.

Altogether, several results of τ1τ2-δ semiconnectedness and compactness in a bitopological space have been discussed.
