Coefficient Inequalities of <em>q</em>-Bi-Univalent Mappings Associated with <em>q</em>-Hyperbolic Tangent Function

The present study introduces a new family of analytic functions by utilizing the <i>q</i>-derivative operator and the <i>q</i>-version of the hyperbolic tangent function. We find certain inequalities, including the coefficient bounds, second Hankel determinants, and Fekete–Sz...
