On quasi semipre-Ɵ-closed sets in topology

الملخص EN

N.

Levine [8] introduced and investigated the notion of generalized closed set.

It is the object of this paper to o er a new notion of generalized closed set called quasi semipre--closed set.

This class is obtained by generalizing semipre- -closed sets.

We also study and characterize the class of -T1 2 spaces.
