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 ...
