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 anz?, g(z) = b1z + ?? n=2 bnz?, b1 < 1 } where h(z) and g(z) are analytic. Additionally f(z) ? SH(?) ? | 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 = ...
