Resumen de On some maps concerning gβθ-open sets

Miguel Caldas Cueva, Saeid Jafari

• In this paper, we consider a new notion of βθ-open maps via the concept of gβθ-closed sets which we call approximately βθ-open maps. We study some of its fundamental properties. It turns out that we can use this notion to obtain a new characterization of βθ-Ti spaces.
