Abstract

In this study, we introduce a new class of bi-univalent functions using q-Ultraspherical polynomials. We derive the Fekete and Szegö functional problems for functions in this new subclass, as well as estimates for the Taylor-Maclaurin coefficients |α₂| and |α₃|. Furthermore, a collection of fresh outcomes is presented by customizing the parameters employed in our initial discoveries.
