Study of a new class for higher-order derivatives of harmonic multivalent functions
Abstract
In this paper, we define and investigate a new class for higher-order derivatives of harmonic multivalent functions. We obtain coefficient inequalities, distortion bounds, extreme points, convex combination. Our results extend corresponding previously known results.
