Abstrakt: The present paper introduces a new class of bi-univalent functions defined on a symmetric domain using Gegenbauer polynomials. For functions in this class, we have derived the estimates of the Taylor–Maclaurin coefficients, a 2 and a 3 , and the Fekete-Szegö functional. Several new results follow upon specializing the parameters involved in our main results. [ABSTRACT FROM AUTHOR]
