Abstract

In this paper, involving a convolution \(f\ast g\), two classes of normalized analytic functions \(f\) are defined. Showing an inclusion relation between these classes, various sufficient conditions for functions to be in these classes are established. In particular, varied forms of univalency conditions of the convolution function \(f\ast g\) are given which lead to some univalency conditions of several linear operators.
