Abstract
For a topological space its reflection in a class of topological spaces is a pair consisting of a space and continuous map such that for any continuous map to a space there exists a unique continuous map such that . In this paper for an infinite cardinal and a nonempty set of ultrafilters on , we study the reflections of topological spaces in the classes of -bounded Hausdorff spaces and of -compact Hausdorff spaces (a topological space is -bounded if the closures of subsets of cardinality in are compact; is -compact if any function has a -limit in for every ultrafilter ).
