Coefficient estimates for a new subclasses of λ-pseudo biunivalent functions with respect to symmetrical points associated with the Horadam Polynomials

Abstract

In the present article, we introduce two new subclasses of λ-pseudo biunivalent functions with respect tosymmetrical points in the open unit disk U defined by means of the Horadam polynomials. For functions belonging tothese subclasses , estimates on the Taylor -Maclaurin coefficients ja2j and ja3j are obtained . Fekete–Szegö inequalitiesof functions belonging to these subclasses are also founded. Furthermore, we point out several new special cases of ourresults.
