Resumen de Some results and examples concerning Whyburn spaces

Ofelia T. Alas, Maira Madriz Mendoza, Richard G. Wilson

• We 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.
