A method for embedding certain countable spaces into a pseudocompact Tychonoff space of countable tightness is given. In particular, this permits construction under [CH] of two pseudocompact Tychonoff spaces of countable tightness, one does not have countable fan tightness and the other contains a non-discrete extremally disconnected subspace.

Abstract
A method for embedding certain countable spaces into a pseudocompact Tychonoff space of countable tightness is given. In particular, this permits construction under [CH] of two pseudocompact Tychonoff spaces of countable tightness, one does not have countable fan tightness and the other contains a non-discrete extremally disconnected subspace.File in questo prodotto:
