Abstract

In the present work, we define a new subclass of meromorphic functions by using newly defined $(p,q)$-differential operator and some geometrical properties such as Sufficiency criteria, coefficient estimates, distortion bounds, radius of starlikeness, radius of convexity and partial sums are discussed for these subclass.

Keywords and Phrases

Regular and Meromorphic functions, Ruscheweyh and Salagean derivative, Janwoski function and $(p,q)$-differential operator.

A.M.S. subject classification

30C45, 30C50.
