Abstract: The object of this paper is to prove new some results about the class $M(n,\alpha)$ of analytic functions $f(z)$ in the unit disk, defined by Ruscheweyh derivatives $D^nf(z)$. That is, a property of the class $M(n,\alpha)$ and the subordination theorems for Ruscheweyh derivatives $D^n f(z)$ are shown.

Classification (MSC2000): 30C45
