Abstract

In this paper, we introduce and study certain subclasses of analytic functions involving Salagean operator. For these classes, the FeketeSzego type coefficient inequalities associated with the ¨ k-th root transformation £f(zk)¤ 1kare derived. A similar problems are investigated for zf(z)when f(z) belonging to these classes.
