Fekete-Szego Type Coefficient Inequalities for Certain Subclasses of Analytic ¨ Functions Involving Salagean Operator

Hanan Darwish, Abdel Moneim Lashin, Suliman Soileh

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(z k ) ¤ 1 k are derived. A similar problems are investigated for z f(z) when f(z) belonging to these classes.
