Bi-Univalency of m-Fold Symmetric Functions Associated with a Generalized Distribution

The m-fold symmetric in terms of a generalized distribution series has not been considered in the literature. In this study, however, the authors investigated the bi-univalency of m-fold symmetric functions for the generalized distribution of two subclasses of analytic functions. The initial few coefficient bounds |a(m )/ S| and |a(2)m/S| are obtained for the two subclasses of functions defined and the results serve as a new generalization in this direction.
