Title

Hankel determinant for a class of analytic functions of complex order defined by convolution

Authors ,

Abstract

In this paper, we obtain the Fekete-Szego inequalities for the functions of complex order defined by convolution. Also, we find upper bounds for the second Hankel determinant |a2a4−a32| for functions belonging to the class Sγb(g(z);A,B).

Keywords

ENG
Fekete-Szego inequality, second Hankel determinant, convolution, complex order.
