A regular topological space having no closed subsets of cardinality $\aleph\sb 2$
Proceedings of the American Mathematical Society1991Vol. 111(4), pp. 1151–1151
Abstract
Using 0^+ , we construct a regular topological space in which all closed sets are of cardinality either 2 .In particular (answering a question of Juhsz) there is always a regular space in which no closed set has cardinality H2 .
