Remarks on \(S\)-closedness in topological spaces. (English) Zbl 1139.54002

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.
