On a New Subclass of m-Fold Symmetric Biunivalent Functions Equipped with Subordinate Conditions

[摘要] In this paper, we introduce a new subclass of biunivalent function class $\Sigma$ in which both $f(z)$ and $f^{-1}(z)$ are m-fold symmetric analytic functions. For functions of the subclass introduced in this paper, we obtain the coefficient bounds for $|a_{m+1}|$ and $|a_{2m+1}|$ and also study the Fekete-Szegö functional estimate for this class. Consequences of the results are also discussed.
