On a new subclass of harmonic meromorphic functions wıth fixed residue ?

Abstract

We use the differential operator Dn,µ ?,?,? to introduce a new class SHn,?,?,? ?,?,?,µ (w, k, ?) of meromorphic harmonic functions with fixed residue ? in Uw. Then we give the coefficient estimates, distortion theorem and extreme points of classes SHn,?,?,? ?,?,?,µ (w, k, ?) and SHn,?,?,? ?,?,?,µ [w, k, ?].
