Coefficient Estimates for Two Subclasses of Analytic and Bi-Univalent Functions

Coefficient Estimates for Two Subclasses of Analytic and Bi-Univalent Functions

We introduce two new subclasses of the class σ of analytic and bi-univalent functions in the open unit disk U. Furthermore, we establish estimates for the first two Taylor–Maclaurin coefficients |a 2 | and |a 3 | of the functions from these new subclasses.
