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

  • Published:
Ukrainian Mathematical Journal Aims and scope

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 |a2| and |a3| of the functions from these new subclasses.
