S-closedness in bitopological spaces

1982
S-closedness is introduced and investigated in bitopological spaces. A topological space (X,T) is S-closed if for every semi-open cover \(\{U_{\alpha}| \alpha \in A\}\) of X, there exists a finite subset B of A such that \(X=\cup \{\bar U_{\alpha}| \alpha \in B\}\) [\textit{T. Thompson}, Proc. Am. Math. Soc. 60, 335-338 (1977; Zbl 0339.54020)].
