Abstract

We introduce new classes, Ξ£βˆ—,πœ‡,π‘˜π‘›,πœ†(𝛼,𝛽,𝜌) and Ξ£πœ‡,π‘˜π‘›,πœ†(𝛼,𝛽,𝜌), of meromorphic functions defined by means of the Hadamard product of Cho-Kwon-Srivastava operator, and we define here a similar transformation by means of an operator given by Ghanim and Darus, in π‘ˆ={π‘§βˆΆ0<|𝑧|<1}, and investigate a number of inclusion relationships of these classes. We also derive some interesting properties of these classes.
