| 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.
