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 ...
New classes of harmonic functions defined by fractional operator
(Işık University Press, 2018)
In the present study, we introduce an investigation of new subclasses of harmonic functions which are defined by fractional operator. Firstly, using by fractional operator, we define new subclasses of harmonic functions. ...
Subclass of m-quasiconformal harmonic functions in association with Janowski starlike functions
(Elsevier Science Inc, 2018-02-15)
Let's take f(z) = h (z) + <(g(z))over bar> which is an univalent sense-preserving harmonic functions in open unit disc D = {z : vertical bar z vertical bar < 1}. If f (z) fulfills vertical bar w(z)vertical bar = ...
Harmonic mappings related to the m-fold starlike functions
(Elsevier Science Inc, 2015-09-15)
In the present paper we will give some properties of the subclass of harmonic mappings which is related to m-fold starlike functions in the open unit disc D = {z parallel to z vertical bar < 1}. Throughout this paper we ...
Notes on Harmonic Functions for which the second Dilatation is α - spiral
(Eudoxus Press, 2015-06)
In this study, we consider, f = h + (g) over bar harmonic functions in the unit disc D. By applying S. S. Miller and P. M. Mocanu result, we obtain a new subclass of harmonic functions, such as S-HPST*(alpha, beta) We ...
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 ...
Harmonic function for which the second dilatation is α-spiral
(Springer International Publishing AG, 2012)
Let f = h + (g) over bar be a harmonic function in the unit disc . We will give some properties of f under the condition the second dilatation is alpha-spiral.
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).
