Abstract

In this article we have introduced a class \(\mathcal {\tilde {R}}_{\varSigma }(\eta ,q,\varsigma ),\eta \in \mathbb {C}-\{0\} \) of bi-univalent functions defined by symmetric q-derivative operator. We have estimated the upper bounds for the initial coefficients and Fekete- Szeg\(\ddot {o}\) inequality by making use of Chebyshev polynomials.
