Some applications of a lemma concerning analytic functions having positive real part in the unit disk

Abstract

In this paper we give some applications of a lemma of Babalola and Opoola [3], which is a classical extension of an earlier one by Lewandowski, Miller, Zlotkiewicz [9]. The applications were given via a new generalization of some well known subclasses of univalent functions, and they unify many known results
