Coefficient bounds for new subclasses of bi-univalent functions. (English) Zbl 1324.30017

Summary, modified: We consider two new subclasses of bi-univalent functions defined in the open unit disk. Besides, we find upper bounds for the second and third coefficients for functions in these new subclasses.
