Some results and examples concerning Whyburn spaces
Keywords:Whyburn space, Weakly Whyburn space, Submaximal space, Scattered space, Semiregular, Feebly compact
AbstractWe prove some cardinal inequalities valid in the classes of Whyburn and hereditarily weakly Whyburn spaces and we construct examples of non-Whyburn and non-weakly Whyburn spaces to illustrate that some previously known results cannot be generalized.
