Quasi-Subordinations for Certain Subclasses of Bi-univalent functions

Öz

In this present investigation, a new class of bi-univalent functions associated with quasi-subordination is defined and the bounds on the first two Taylor-Maclaurin coefficients |a_2| and |a_3|  for functions belonging to this class are derived. Furthermore, several related classes of functions are also indicated.
