AbstractWe show that every closed subset of an M1-space has a closure-preserving open neighborhood base. This answers a question of Ceder, and gives positive solutions to other problems on adjunction spaces and countable sums of M1-spaces
AbstractA set A in a topological space X is called κ-closed if B⊂A whenever B⊂A and |B|<κ. A κ-hole ...
