2. Some Properties of Certain New Classes of Analytic Functions Defined By a Generalized Differential Operator by Oyekan E. A. Transactions of NAMP Vol. 5,(Sept and Nov., 2017), pp 11 – 22
Abstract
In this work we investigate certain new classes of analytic functions defined by a generalized differential operator. The sufficiency conditions for a function to belong to these classes are investigated and some other properties of these classes of functions are obtained as well. Several interesting consequences of the main results are also mentioned.
