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.

Palabras clave

Topological spaces ; βθ-closed sets ; βθ-open sets ; βθ-open maps ; β-irresolute maps ; βθ-T1 spaces.
