摘要：
In F.M. Al-Oboudi, On univalent functions defined by a generalized Salagean operator, Indian J. Math. Math. Sci. 25-28 (2004), pp. 1429-1436, by using the operator D(lambda)(n)f(z), z epsilon U, (Definition 3), the author introduces a class of univalent functions denoted by R-n(lambda, alpha). Some convolution properties of functions belonging to R-n(lambda, alpha) and other results are given. In this article we obtain certain differential subordinations related to this class and we give the best dominants.
