| $\beta$-connectedness and $\Cal S$-connectedness of topological spaces |
| Zbigniew Duszyński |
Abstract Characterizations of $\beta$-connectedness and $\Cal S$-connectedness of topological spaces are investigated. Further results concerning preservation of these connectedness-like properties under surjections are obtained. The paper completes our previous study [Z. Duszyński, {\it On some concepts of weak connectedness of topological spaces}, Acta Math. Hungar. {\bf 110} (2006), 81--90].
