On a new subclass of harmonic meromorphic functions wıth fixed residue ξ
(Işık University Press, 2014)
We use the differential operator Dn,µ λ,δ,φ to introduce a new class SHn,γ,β,ξ λ,δ,φ,µ (w, k, α) of meromorphic harmonic functions with fixed residue ξ in Uw. Then we give the coefficient estimates, distortion theorem and ...
Some results on a starlike log-harmonic mapping of order alpha
(Elsevier Science BV, 2014-01-15)
Let H(D) be the linear space of all analytic functions defined on the open unit disc D = z is an element of C : vertical bar z vertical bar < 1. A sense preserving log-harmonic mapping is the solution of the non-linear ...
Quasiconformal harmonic mappings related to Janowski alpha-spirallike functions
(Amer Inst Physics, 2014)
Let f = h(z) + g(z) be a univalent sense-preserving harmonic mapping of the open unit disc D = {z/vertical bar z vertical bar < 1}. If f satisfies the condition vertical bar omega(z)vertical bar = vertical bar g'(z)/h'(z)vertical ...
A certain class of starlike log-harmonic mappings
(Elsevier Science BV, 2014-11)
In this paper we investigate some properties of log-harmonic starlike mappings. For this aim we use the subordination principle or Lindelof Principle (Lewandowski (1961) [71).
