The further unified theory for modifications of \(g\)-closed sets (Q1032578)

This paper aims at a unified theory of \(g\)-cosed sets. A typical result is the following Theorem: Let \(m_X\) and \(n_X\) be minimal structures on a nonempty set \(X\). Let \(n_X\) have property \({\mathcal B}\). A bi-\(m\)-space \((X,m_X,n_X0\) is \(mn\)-\(T_{{1\over 2}}\) if and only if every \(mng\)-closed set of \(X\) is \(n_X\)-closed. The notions of \((m,n)\)-normal spaces and new forms of \(mng\)-closed sets are also introduced.
