Abstract

In the present paper, we investigate the issue of coefficient estimates in subclasses of bi-univalent  functions, where an estimate for the second Hankel determinant in the subclass  , which is defined  by  Murugusundaramoorthy  (2013),  was obtained.  Also, an estimate for coefficient  in  the subclass  ,  which  is defined by Frasin (2014), was found. Moreover, estimates for both coefficient  and the second Hankel determinant in the subclass were obtained.
