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 |a_2a_4-a_3^2| for functions belonging to the class S_γ^b(g(z);A,B).
Keywords: Fekete-Szego inequality, second Hankel determinant, convolution, complex order.
