An investigation of the certain class of multivalent harmonic mappings
Polatoğlu, Yaşar; Özkan Uçar, Hatice Esra; Aydoğan, Seher Melike (2016)The main purpose of the present paper is to investigate some properties of the certain class of sensepreserving pvalent harmonic mappings in the open unit disc D = {z is an element of C parallel to z vertical bar < 1}. 
Closetoconvex functions defined by fractional operator
Aydoğan, Seher Melike; Kahramaner, Yasemin; Polatoğlu, Yaşar (2013)Let S denote the class of functions f(z) = z + a2z2 + ... analytic and univalent in the open unit disc D = {z ∈ Cz < 1}. Consider the subclass and S∗ of S, which are the classes of convex and starlike functions, ... 
Harmonic mappinggs for which coanalytic part is a closetoconvex function of order b
Polatoğlu, Yaşar; Kahramaner, Yasemin; Aydoğan, Seher Melike (2015)In the present paper we investigate a class of harmonic mappings for which the second dilatation is a closetoconvex function of complex order b, b ∈ C/{0} (Lashin in Indian J. Pure Appl. Math. 34(7):11011108, 2003).

Harmonic mappings related to Janowski convex functions of complex order b
Aydoğan, Seher Melike; Polatoğlu, Yaşar; Kahramaner, Yasemin (201301)Let SH be the class of all sensepreserving harmonic mappings in the open unit disc D = {z ∈ ℂz < 1}. In the present paper the authors investigate the properties of the class of harmonic mappings which is based on the ... 
Notes on Starlike logHarmonic Functions of Order alpha
Aydoğan, Seher Melike; Yavuz Duman, Emel; Owa, Shigeyoshi (2013)For logharmonic functions f(z) = zh(z)g(z) in the open unit disk U, two subclasses H∗ LH(α) and G∗ LH (α) of S∗ LH(α) consisting of all starlike logharmonic functions of order α (0 ≤ α < 1) are considered. The object ...

Some Properties of qConvex Functions of Complex Order
Polatoğlu, Yaşar; Aydoğan, Seher Melike; Mert, Oya (2017)Let A be the family of functions f(z) which are regular in the open unit disc D = {z : z < 1} and satisfy the conditions f(0) = 0, f 0 (0) = 1 for every z ∈ D and let f(z) be an element of A, if f(z) satisfies the ... 
Some properties of starlike harmonic mappings
Aydoğan, Seher Melike; Yemişçi, Halime Arzu; Polatoğlu, Yaşar (Springer International Publishing Ag, Gewerbestrasse 11, Cham, Ch6330, Switzerland, 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*, ...
