Harmonic mappings related to Janowski starlike functions
(Elsevier Science BV, 2014-11)
The main purpose of the present paper is to give the extent idea which was introduced by Robinson(1947) [6]. One of the interesting application of this extent idea is an investigation of the class of harmonic mappings ...
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 ...
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 ...
Bounded harmonic mappings related to starlike functions
(Amer Inst Physics, 2014-12-17)
Let f = h(z) + <(g(z))over bar> be a sense-preserving harmonic mapping in the open unit disc D = {z vertical bar vertical bar z vertical bar < 1}. If f satisfies the condition vertical bar 1/b(1) g'(z)/h' (z) - M vertical ...
Extensions for certain subordination relations
(Işık University Press, 2014)
For some complex number ? which has a positive real part, a certain subordination relation concerned with the Bernardi integral operator I? was proven by D. J. Hallenbeck and St. Ruscheweyh (Proc. Amer. Math. Soc. 52(1975), ...
New sufficient conditions for starlike and convex functions
(Işık University Press, 2014)
Let A be the class of analytic functions f(z) in the open unit disc. Applying the subordination, some sufficient conditions for starlikeness and convexity are discussed.
An investigation of the certain class of multivalent harmonic mappings
(Eudoxus Press, 2016-03)
The main purpose of the present paper is to investigate some properties of the certain class of sense-preserving p-valent harmonic mappings in the open unit disc D = {z is an element of C parallel to z vertical bar < 1}.
On the Chebyshev polynomial coefficient problem of bi-Bazilevi? functions
(Işık University Press, 2020)
A function said to be bi-Bazilevi? in the open unit disk U if both the function and its inverse are Bazilevi? there. In this paper, we will study a newly constructed class of bi-Bazilevi? functions. Furthermore, we establish ...
A new subclass of bi-univalent functions defined by q-derivative
(Işık University Press, 2019)
In this investigation we introduce, by making use of q−derivative operator, a new subclass which are an extension of some well-known subclasses of bi-univalent functions. Also, we give the upper bounds for the coefficients ...
Subclasses of multivalent functions of complex order associated with sigmoid function and bernoulli lemniscate
(Işık University Press, 2020)
In this present work, subclasses of multivalent functions of complex order associated with simple logistic sigmoid activation function and Bernoulli Lemniscate were investigated. Early few coefficient bounds, relevant ...
