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 ...
Null biharmonic curves in the Lorentzian Heinsenberg group Heis3
(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
Weierstrass representation formula in the group of rigid motions E(2)
(2010-11-02)
In this paper, we prove a Weierstrass representation formula for simply connected immersed
maximal surfaces in E(2). Using the Weierstrass representation we also give a simple
proof of the fact that maximal immersions is ...
A note on Lanczos generalized derivative
(2010-11-02)
Lanczos introduced an integral expression for calculating the derivative of a function, if
this is continuous in the point x under analysis. Here we extend this expression to the case
of a finite discontinuity at x.
