Abstract

Considering a new subclass of m-fold symmetric analytic bi-univalent functions, we determine estimates the coefficient bounds for the Taylor-Maclaurin coefficients |a_{m+1}| and |a_{2m+1}| of the functions in this class. In certain cases, our estimates improve some of those existing coeffcient bounds.

Keywords
