On a New Subclass of Multivalent Functions Defined by Hadamard Product

Abstract

In this paper we introduce and study the class of multivalent functions in the open unit disk U= {Z  c₁|z|<1} which are defined by the convolution (or Hadamard product). Then we give the coefficient inequality, closure theorems, neighborhoods of theclass ,partial sums, weighted mean theorem, convolution, distortion and growth bounds.
