Abstract

In this letter, we introduce meromorphically starlike functions by using a particular class of analytic functions that present authors applied in 2012 [cf.[1]]. These functions map the punctured unit disk into a starlike domain at infinity. Besides, we investigate coefficient estimate, radii of convexity and distortion theorems as well. Finally, we ascertain that these subclasses are closed under convex linear combination.
