Duszyński, Zbigniew Remarks on \(S\)-closedness in topological spaces. (English) Zbl 1139.54002 Boll. Unione Mat. Ital., Sez. B, Artic. Ric. Mat. (8) 10, No. 2, 469-483 (2007). Some properties of \(S\)-closed subsets and relatively \(S\)-closed subsets in topological spaces are discussed; they include mapping properties about certain \(S\)-closed subsets and relations between \(S\)-closed subspaces and weak connectedness.
