Horadam polynomials for a new subclass of Sakaguchi-type Bi-univalent functions defined by (P, Q)-derivative operator

Abstract

In this paper, a new subclass, SC mu ,p,q sigma (r, s; x), of Sakaguchitype analytic bi-univalent functions defined by (p, q)-derivative operator using Horadam polynomials is constructed and investigated. The initial coefficient bounds for | a 2 | and | a 3 | are obtained. Fekete-Szeg & ouml; inequalities for the class are found. Finally, we give some corollaries.
