On \(P\)-closedness in a bitopological space (Q934514)

The following are some of the results contained in this paper: {\parindent=16mm \begin{itemize}\item[Result] In an \(ij\)-\(P\)-closed space \(X\), an \(ij\)-\(p(\theta)\)-closed set is \(ij\)-\(P\)-closed relative to \(X\). \item[Result] Let \(X\) be a pairwise Urysohn space and \(A\subset X\) be \(ij\)-\(P\)-closed relative to \(X\). Then \(A\) is \(ji\)-\(p(\theta)\)-closed. \end{itemize}} Characterization of an \(ij\)-\(P\)-closed set \(A\), relative to \(X\), is given in terms of a maximal filter-base, net, ultranet and so on.
