A class of multivalent harmonic functions involving a generalized Ruscheweyh type operator. (English) Zbl 1224.30034

Authors’ abstract: “A class of \(p\)-valent harmonic functions associated with a certain generalized Ruscheweyh type operator is introduced. Among various properties investigated for this class of functions are the results giving the coefficient bounds, distortion properties and extreme points.”
