Abstract

In this paper, we have investigated second Hankel determinants and Fekete-Szegö inequalities for some subclasses of Bi-univalent functions with respect to symmetric and Conjugate points which are subordinate to a shell shaped region in the open unit disc ∆.

Keywords:

Analytic functions univalent functions Bi-univalent functions second Hankel determinants Fekete-Szegö inequalities symmetric points conjugate points.
