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) ... -
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 = ...
