Contra g-alpha- and g-beta-preirresolute functions on GTS's

Abstract

In this present paper, we define g-alpha-preirresolute, g-beta-preirresolute, contra g-alpha-preirresolute and contra g-beta-preirresolute functions on generalized topological spaces. We give some examples of this definitions. We investigate some properties and characterizations of this functions.
