(English) Zbl 1463.54064 Bull. Int. Math. Virtual Inst. 9, No. 2, 231-244 (2019). Summary: \(\mathcal{I}_{w\widehat{g}}\)-normal and \(\mathcal{I}_{w\widehat{g}}\)-regular spaces are introduced and various characterizations and properties are given. Characterizations of normal, mildly normal, \(w\widehat{g}\)-normal and regular spaces are also given. MSC: 54D10 Lower separation axioms (\(T_0\)–\(T_3\), etc.) 54D15 Higher separation axioms (completely regular, normal, perfectly or collectionwise normal, etc.) Keywords:\(\mathcal{I}_{w\widehat{g}}\)-closed set; \(\mathcal{I}_{w\widehat{g}}\)-open set; completely codense ideal; \(w\widehat{g}\)-closed set; \(w\widehat{g}\)-open set; \(w\widehat{g}\)-normal space; mildly normal space; regular space PDFBibTeX XMLCite \textit{T.
