Abstract

In this paper we introduce and study a subclass of meromorphically univalent functions defined by generalized Liu-Srivastava operator. We obtain coefficient estimates, extreme points, growth and distortion bounds, radii of meromorphic
starlikeness and meromorphic convexity for the defined class by fixing the second coefficient. Further, it is shown that the class is closed under convex linear combination.
