Abstract

In this paper, we introduce and investigate a new subclass of the analytic and bi-univalent functions in the open unit disk in the complex plane.For the functions belonging to this class, we obtain estimates on the Örstthree coe¢ cients in their Taylor-Maclaurin series expansion. Some interestingcorollaries and applications of the results obtained here are also discussed.
