On discrete and disjoint shrinking properties

Vladimir Tkachuk ⟨vvtmdf@gmail.com⟩

Abstract:

A space X has the disjoint (discrete) shrinking property if for any family Un:nω of non-empty open subsets of X there exists a disjoint (discrete) family Vn:nω of non-empty open sets such that VnUn for every nω. We present a topological equivalent of the disjoint shrinking property in general spaces and apply it to characterize the disjoint shrinking property in topological groups and locally convex spaces.
