On a Janowski formula based on a generalized differential operator

Abstract

The central purpose of the current paper is to consider a set of beneficial

possessions including inequalities for a generalized subclass of Janowski functions (analytic

functions) which are formulated here by revenues of a generalized Sàlàgean’s differential operator.

Numerous recognized consequences of the outcomes are also indicated

Keywords
