Some properties of starlike harmonic mappings
Aydoğan, Seher Melike; Yemişçi, Arzu; Polatoğlu, Yaşar (Springer International Publishing AG, 2012)A fundamental result of this paper shows that the transformation F=az(h(z+a/1+(a) over barz) + /(h(a) + <(g(a))over bar>(z + a) (1 + (a) over barz) defines a function in S0 HS* whenever f = h( z) + g( z) is S0 HS*, andwewill ... -
Some results on a starlike log-harmonic mapping of order alpha
Aydoğan, Seher Melike (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 ... -
Some results on a subclass of harmonic mappings of order alpha
Varol, Dürdane; Aydoğan, Seher Melike; Owa, Shigeyoshi (Işık University Press, 2014)Let SH be the class of harmonic mappings defined by SH = { f = h(z) + g(z)| h(z) = z + ∑∞ n=2 anzⁿ, g(z) = b1z + ∑∞ n=2 bnzⁿ, b1 < 1 } where h(z) and g(z) are analytic. Additionally f(z) ∈ SH(α) ⇔ | zh′ (z) − zg′(z) h(z) ... -
Some results on a subclass of multivalent harmonic mappings
Öztürk, Durdane (Işık Üniversitesi, 2015)In this thesis, the fundamental function classes and their properties are introduced. Some results that we can generalize to multivalent functions are obtained. Next, as the main part of the study, a new subclass of ... -
Subclass of m-quasiconformal harmonic functions in association with Janowski starlike functions
Sakar, Fethiye Müge; Aydoğan, Seher Melike (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 = ...
