New differential subordinations obtained by using a differential-integral Ruscheweyh-Libera operator
Georgia Irina Oros;Abstract
In this paper, a differential-integral operator is defined using Ruscheweyh differential operator and Libera integral operator. By using the operator, a class of univalent functions is defined and several differential subordinations are studied.
