Results and problems concerning compactifications, compact subtopologies, and mappings
Selections and approaching points in products
The present paper aims to furnish simple proofs of some recent results about selections on product spaces obtained by García-Ferreira, Miyazaki and Nogura. The topic is discussed in the framework of a result of Katětov about complete normality of products. Also, some applications for products with a countably compact factor are demonstrated as well.
Semilattice theory with applications to point-set topology
Semilocal connectedness of product spaces and -continuity of maps.
Semitopological properties
Sequential space methods in general topological spaces
Sequentially determined convergence spaces
Skula spaces
Small sets with respect to certain classes of topologies
Some more properties of and regular -closed sets in ideal topological spaces.
Some properties of the density topology with respect to an extension of the Lebesgue measure.
Some properties of the topology of -sets
Some subsets of ideal topological spaces
Spaces in which compact subsets are closed and the lattice of -topologies on a set
We obtain some new properties of the class of KC-spaces, that is, those topological spaces in which compact sets are closed. The results are used to generalize theorems of Anderson [1] and Steiner and Steiner [12] concerning complementation in the lattice of -topologies on a set .
