Waggas Galib Atshan [13] | Ali Hussein Battor [3] | Azhar Jawad Kadhim
Abstract: In this paper, we have discussed a subclassS (, , , ,) of analytic and univalent function with negative coefficients defined by Ruscheweyh derivative in unit diskU={z-C-|z|<1}. We obtain basic properties like coefficient inequality, distortion theorem, extreme points and radii of starlikeness, convexity and close-to-convexity, Hadamard productand convolution operator.
