Topological equivalences of $$\mathbf {CUT}$$ CUT and $$\mathbf {CUT}$$ CUT
Archive for Mathematical Logic 55 (7-8):867-872 (2016)
Abstract
In this note, two well-known topological facts regarding cofinite and cocountable-like topologies over uncountable sets are shown to be equivalent either to the Countable Union Theorem or to the Countable Union Theorem for countable families of finite sets.My notes
