On e*θ-regular and e*θ-normal Spaces

The purpose of this study is to introduce a new class of regular spaces called e*θ-regular spaces which is a generalization of the class of βθ-regular spaces. Also, we investigate some basic properties and several characterizations of e*θ-regular and e*θ-normal spaces. Moreover, some functions such as e*θ-closed function, generalized e*θ-closed function, generalized e*θ-closed function have been defined and studied. Furthermore, we obtain some preservation theorems.
