Abstract

Motivated by work of Srivastava-Owa, we define new generalized subclasses of bi-univalent functions defined in the open unit disk which are associated with fractional differential operator. Furthermore, we have obtained estimates of the coefficients $|a_{2}|$ and $|a_{3}|$ for the functions belonging to these subclasses.

Keywords and Phrases
