Autor: Alas, Ofelia T.; Madriz-Mendoza, Maira; Wilson, Richard G.
Resumen: [EN] 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.
