Lipparini, Productive $[λ,μ]$-compactness and regular ultrafilters, Topology Proceedings, 21 (1996), 161--171"; in particular the present results apply to singular cardinals, too.6 pagesGeneral TopologyLogic03E05, 54B10, 54D20, 54A20 (Primary); 03E75 (Secondary)Combinatorial and model-theoretical principles related to regularity of ultrafilters and compactness of topological spaces.
