Coefficient estimates for a general subclass of $m$fold symmetric biunivalent functions
A. Motamednezhad, S. Salehian
In the present paper, we introduce and investigate an interesting subclass ${\mathcal B}_{{\Sigma}_m}^{h,p}(\lambda,\gamma)$
of $m$fold symmetric biunivalent functions in the open unit disk $\mathbb{U}$. Furthermore, we obtain estimates on
the coefficients $a_{m+1}$ and $a_{2m+1}$ for functions belonging to this subclass.
The results presented in this paper would generalize and improve some recent works of several earlier authors.
