Inclusion properties of certain subclasses of analytic functions
(SABER-ULA, 2011-06-30)
The purpose of the present paper is to introduce several new classes of analytic functions
and investigate various inclusion properties of these classes. Some interesting applications of
integral operators are also considered.
Characterization inextensible flows of developable surfaces associated focal curve of spacelike curve with timelike binormal in E31
(SABER-ULA, 2011-06-30)
In this paper, we study inextensible flows of developable surfaces associated with focal
curves of spacelike curves with timelike binormal in Minkowski 3-space E3
1 . We show that if
flow of this developable surface is ...
Geometrical inequalities unconventional demonstrated
(2011-01-11)
In this paper we have synthetized more geometric inequalities at which we can give unconventional solutions. The applications and some solutions are selected from the bibliography attached to this paper. We consider that ...
On characterization dual spacelike biharmonic curves with spacelike principal normal according to dual Bishop frames in the dual Lorentzian space D3 1
(2011-01-11)
In this paper, we study dual spacelike biharmonic curves with spacelike principal normal in dual Lorentzian space D3 1: We characterize curvature and torsion of dual spacelike biharmonic curves with spacelike principal ...
On some series of functions
(2011-01-11)
The study of the Fourier series convergence is a frequent subject in the speciality literature (see [3], [4]). It is known that the Fourier series convergence is very useful in the technical problems: the electromagnetic ...
On some parametric representations of certain analytic and meromorphic classes on the complex plane
(2010-11-30)
We introduce and study certain new scales of analytic and meromorphic functions in the
unit disc and solve some problems in these scales. We provide complete descriptions of zero
sets, then we present some new parametric ...
Bertrand mate of null biharmonic curves in the Lorentzian Heisenberg group Heis.
(2010-11-30)
In this paper, we study null biharmonic curves and we characterize null biharmonic curves
in terms of their curvature and torsion in the Lorentzian Heisenberg group Heis3. Moreover,
we construct parametric equations of ...

(2010-11-30)
In this paper, we study biharmonic curves and we characterize null biharmonic curves
in terms of their curvature and torsion in the Lorentzian Heisenberg group Heis3. We give
necessary and sufficient conditions for null ...
Mannheim curves in terms of its timelike biharmonic partner curves in the Lorentzian Heisenberg Group Heis3
(2010-11-30)
In this paper, we study Mannheim curves in the Lorentzian Heisenberg group Heis3. We
characterize Mannheim curves in terms of its horizontal biharmonic partner curves in the
Lorentzian Heisenberg group Heis3
