Özet

In this work, we introduce and investigate two new subclasses of the bi-univalent functions in which both f and f(-1) are m-fold symmetric analytic functions. For functions in each of the subclasses introduced in this paper, we obtain the coefficient bounds for vertical bar a(m+1)vertical bar and vertical bar a(2m+1)vertical bar.
