|Normality and property (a)|
A space X is said to have property (a) if for each open cover U and each dense , there is a closed discrete such that . This property was recently introduced by M. Matveev and is of particular interest when X is countably compact. Although not a priori obvious, property (a) is closely related to normality. I will discuss recent theorems, examples and open questions.
