Some Applications on Subclasses of Analytic Functions Involving Linear Operator

Abstract

The object of this paper is to give some applications of differential subordination concept on subclasses of univalent functions for some convolution operators which are defined on the space of univalent meromorphic functions in the punctured open unit disc. Moreover, we derive some sandwich theorems, we study some geometric properties like coefficient bounds, distortion theorem, and radii of starlikeness and convexity for these classes of functions. Extreme points and integral operator are also investigated.
