Abstract

 

This paper introduces and investigate a new subclasses of the class  of analytic functions that both are -fold symmetric -univalent functions in the open unit disk  and get the estimates of the initial coefficients  for functions in each of these new subclasses. After this, the work will be discussing the Hankel determinant and a Fekete-Szegö functional.

 

Keywords:  Analytic function; univalent function; -univalent functions;  symmetric -univalent functions; Hankel determinant; Fekete-Szegö functional.
