#### lambda-fractional close-to-convex functions

(International Symposium on Geometric Function Theory and Applications, 2007, Istanbul Kültür University, Istanbul, Turkey, 2007)

#### Some distortion theorems for starlike log-harmonic functions

(International Short Joint Research Workshop, Applications of Convolutions in Geometric Function Theory, 2011, Research Institute for Mathematical Sciences, Kyoto University (RIMS), Kyoto, Japan, RIMS Kokyuroku, 2011-12)

#### An investigation on a new class of harmonic mappings

(Springer International Publishing Ag, Gewerbestrasse 11, Cham, Ch-6330, Switzerland, 2013)

In the present paper, we give an extension of the idea which was introduced by Sakaguchi (J. Math. Soc. Jpn. 11:72-75, 1959), and we give some applications of this extended idea for the investigation of the class of harmonic ...

#### Some distortion theorems for starlike harmonic functions

(2010)

In this paper , we consider harmonic univalent mappings of the form f = h + ¯g defined on the unit disk D which are starlike. Distortion and growth theorems are obtained.

#### An investigation on a subclass of p-valently starlike functions in the unit disc

(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, ATATURK BULVARI NO 221, KAVAKLIDERE, TR-06100 ANKARA, TURKEY, 2007)

Let A(p) denote the class of functions of the form f(z) = z(p) +a(p+1)z(p+1)+a(p+2)z(p+2) +... which are regular and p-valent in the open unit disc D = {z : vertical bar z vertical bar < 1}. Let M-p(alpha) be the subclass ...

#### Application Of The Subordination Principle To The Multivalent Harmonic Mappings With Shear Construction Method

(Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2011-06)

The harmonic function in the open unit disc D = (z is an element of C vertical bar z vertical bar < 1} can be written as a sum of an analytic and an anti-analytic function. f = h(z) + g(z), where h(z) and g(z) are analytic ...

#### Harmonic Function For Which The Second Dilatation is Alpha-Spiral

(Springer International Publishing Ag, Gewerbestrasse 11, Cham, Ch-6330, Switzerland, 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

#### Harmonic mappinggs for which co-analytic part is a close-to-convex function of order b

(2015)

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 ∈ C/{0} (Lashin
in Indian J. Pure Appl. Math. 34(7):1101-1108, 2003).

#### Some properties of q- close-to-convex functions

(2017)

Quantum calculus had been used first time by M.E.H.Ismail, E.Merkes
and D.Steyr in the theory of univalent functions [5].
In this present paper we examine the subclass of univalent functions
which is defined by quantum ...

#### Growth and distortion theorems for multivalent Janowski close-to-convex harmonic functions with shear construction method

(Scientific Technical Research Council Turkey-Tubitak, Ataturk Bulvarı No 221, Kavaklıdere, Tr-06100 Ankara, Turkey, 2013)

In this paper we introduce the class of m-valent Janowski close to convex harmonic functions. Growth and distortion theorems are obtained for this class.
Our study is based on the harmonic shear methods for harmonic functions.
