 On a class of analytic functions involving Ruscheweyh derivatives Bull. Korean Math. Soc. 2002 Vol. 39, No. 1, 122-131 Published online March 1, 2002 Yang Dinggong and Liu Jinlin Suzhou University, Yangzhou University Abstract : Let $A(p,k)$ $(p, k \in N)$ be the class of functions $f(z)=z^p + a_{p+k}z^{p+k} + \cdots$ analytic in the unit disk. We introduce a subclass $H(p, k, \lambda, \delta, A, B)$ of $A(p,k)$ by using the Ruscheweyh derivative. The object of the present paper is to show some properties of functions in the class $H(p, k, \lambda, \delta, A, B).$ Keywords : analytic function, Ruscheweyh derivative, convolution, subordination, partial sums MSC numbers : 30C45 Downloads: Full-text PDF
