On the class of harmonic mappings which is related to the class of bounded boundary rotation
(Elsevier Science Inc, 2015-09-15)
The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ...
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 for which co-analytic part is a close-to-convex function of order b
(Springer International Publishing, 2015-01-16)
In the present paper we investigate a class of harmonic mappings for which the second dilatation is a close-to-convex function of complex order b, b is an element of C/{0} (Lashin in Indian J. Pure Appl. Math. 34(7):1101-1108, ...
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 ...
A certain class of harmonic mappings related to functions of bounded boundary rotation
(Eudoxus Press, 2014-05)
Let V(k) be the class of functions with bounded boundary rotation and let S-H be the class of sense-preserving harmonic mappings. In the present paper we investigate a certain class of harmonic mappings related to the ...
Some properties concerning close-to-convexity of certain analytic functions
(Springer International Publishing AG, 2012)
Let f(z) be an analytic function in the open unit disk D normalized with f(0) = 0 and f'(0) = 1. With the help of subordinations, for convex functions f(z) in D, the order of close-to-convexity for f(z) is discussed with ...
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).
