M. Ali, Rosihan (2003) *The Coefficients Of Functions With Positive Real Part And Some Special Classes Of Univalent Functions.* In: Proceedings of the SEAMS-GMU Conference 2003, 14 - 17 July 2003 , Gadjah Mada University, Yogyakarta, Indonesia.

## Abstract

Several special classes of univalent functions f in the unit disk U are characterized by the quantity zf'(z)/ f (z) lies in a given region in the right-half plane. Amongst these are the classes SS• (a) of strongly starlike functions of order a and PS• (p) consisting of parabolic starlike functions of order p. Both classes are closely related to the class P of nonnalized analytic functions in U with positive real part.
