Abstract
In this paper, we introduce the subclasses , A a b c A B n P ( , , ; , , )  and A a b c A B *n ,P ( , , ; , , )  of meromorphic multivalent functions in the punctured unit disk U z z *      £ : 0 1 by using a differential operator ( , ; , ) ( ) , hn p a b c z f z . We obtain coefficient estimates, distortion theorem, radius of convexity and closure Theorems for the class. * , A a b c A B n P ( , , ; , , )
