1. Admissible classes of multivalent functions associated with an integral operator.

Author

SEOUDY, T. M. and AOUF, M. K.

Subjects
*INTEGRAL functions, *ANALYTIC functions, *INTEGRAL operators
Abstract

In this paper we investigate some applications of the differential subordination and superordination of classes of admissible functions associated with an integral operator. Additionally, differential sandwich-type results are obtained. [ABSTRACT FROM AUTHOR]

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

Author

EL-DEEB, S. M. and AOUF, M. K.

Subjects
*HANKEL functions, *ANALYTIC functions, *MATHEMATICAL convolutions
Abstract

In this paper, we obtain the Fekete-Szegö inequalities for the functions of complex order defined by convolution. Also, we find upper bounds for the second Hankel determinant |a2a4 - a2³| for functions belonging to the class Sbγ (g(z); A,B). [ABSTRACT FROM AUTHOR]

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

Author

EL-DEEB, S. M. and AOUF, M. K.

Subjects
*ANALYTIC functions, *MATHEMATICAL convolutions, *HADAMARD matrices, *UNIVALENT functions, *GAMMA functions
Abstract

In this paper, we obtain the Fekete-Szegö inequalities for the functions of complex order defined by convolution. Also, we find upper bounds for the second Hankel determinant ǀa2a4 - a32ǀ for functions belonging to the class Sγp (g(z); A,B). [ABSTRACT FROM AUTHOR]
