الملخص

An investigation into a novel subclass of analytic and bi-univalent functions associated with quasi-subordination in the open unit disk is introduced. The factor estimates |a2 | | a3|, for functions in belonging to these subclasses are established. Furthermore, several relevant consequences and special cases of the main results are highlighted.
