Characterization of Hardly e-Open functions

  • Miguel Caldas Universidade Federal Fluminense
Palabras clave: Topological spaces, e-open sets, e-dense sets, hardly e-open functions


A function is dened to be hardly e-open provided that theinverse image of each e-dense subset of the codomain that is contained in a proper open set is e-dense in the domain. Characterizations and properties of hardly e-open functionsare presented.
