The Fekete-Szegö problem for certain subclass of analytic and univalent functions associated with sine hyperbolic function with complex order

Abstract

In this paper, we give coefficient estimates for the certain subclass of analytic and univalent functions on the open unit disk in the complex plane associated with sine hyperbolic function with the complex order. For the defined here subclass , we obtain coefficient estimates for initial two coefficients and examine the Fekete-Szegö problem.
