In this paper, estimates for second and third MacLaurin coefficients of certain subclasses of bi-univalent functions in the open unit disk defined by convolution are determined, and certain special cases are also indicated. The main result extends and improve a recent one obtained by Srivastava et al. [ABSTRACT FROM AUTHOR]

In this paper, we establish certain results concerning the quasi-Hadamard product for the classes related to meromorphic p-valent analytic functions with positive coefficients. [ABSTRACT FROM AUTHOR]

Abstract: Here we investigate a majorization problem involving starlike function of complex order belonging to a certain class defined by means of fractional derivatives. Relevant connections of the main results obtained in this paper with those given by earlier workers on the subject are also pointed out. [Copyright &y& Elsevier]

In the present paper, we derive certain new argument properties of a class of multivalent analytic functions defined in an open unit disk by using a theorem recently established by A. Y. Lashin in 2004. Certain intersting (known or new) results are derived in the form of corollaries from our main results. [ABSTRACT FROM AUTHOR]

We derive subordination and superordination results for a family of normalized analytic functions in the open unit disk defined by integral operators. We apply this to obtain sandwich results and generalizations of some known results. [ABSTRACT FROM AUTHOR]
