A compact ccc non-separable space from a Hausdorff gap and Martin's Axiom

Comment.Math.Univ.Carolinae 37,3 (1996) 591-596.

Abstract:We answer a question of I. Juhasz by showing that MA $+ \neg $ CH does not imply that every compact ccc space of countable $\pi $-character is separable. The space constructed has the additional property that it does not map continuously onto $I^{\omega _1}$.

Keywords: ccc, non-separable, Hausdorff gap, $\pi $-character
