Multi-Dimensional Weiss Operators
(Scientific Technical Research Council Turkey-Tubitak, Ataturk Bulvari No 221, Kavaklidere, TR-06100 Ankara, Turkey, 2011)
We present a solution of the Weiss operator family generalized for the case of R(d) and formulate a d-dimensional analogue of the Weiss Theorem. Most importantly, the generalization of the Weiss Theorem allows us to find ...
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 ...
On Janowski starlike functions
(Springer International Publishing Ag, Gewerbestrasse 11, Cham, Ch-6330, Switzerland, 2007)
For analytic functions f(z) in the open unit disc U with f(0) = 0 and f'(0) = 1, applying the fractional calculus for f(z), a new fractional operator D-lambda f(z) is introduced. Further, a new subclass F-lambda(*)(A, B) ...
Coefficient inequalities for classes of uniformly starlike and convex functions
In view of classes of uniformly starlike and convex functions in the open unit discUwhich was considered by S. Shams, S.R. Kulkarni and J.M. Jahangiri, some coefﬁcient in-equalities for functions are discussed
A note on certain analytic functions
(International Short Joint Research Workshop, Study on Calculus Operators in Univalent Function Theory, 2007, Research Institute for Mathematical Sciences, Kyoto University (RIMS), Kyoto, Japan, 2007)
Two point distortion theorems and Koebe domain under the Montel normalization for the subclass of starlike functions
(International Symposium on Geometric Function Theory and Applications, GFTA 2011, Babes-Bolyai University, Cluj-Napoca, Romania, 2011)
On generalized Janowski starlike logharmonic
In this paper, we consider univalent logharmonic mappings of the form f(z) = zh(z)g(z) defined on the open unit disc with the normalization condition g(0) = 1 and h(0) 6= 0. We investigate the class of generalized ...
Some New Growth Theorems for Starlike Log Harmonic Functions
