نویسندگان

چکیده

The approach of the paper is on spacelike circular surfaces in Minkowski 3-space. A surface a one-parameter family Lorentzian circles with fixed radius regarding non-null curve, which acts as spine and it has symmetrical properties. In study, we have parametrized provided their geometric singularity properties such Gaussian mean curvatures, comparing them those ruled classification singularities. Furthermore, conditions for roller coaster to be flat or minimal are obtained. Meanwhile, support results some examples.

Spacelike Capillary Surfaces in the Lorentz--minkowski Space

For a compact spacelike constant mean curvature surface with nonempty boundary in the threedimensional Lorentz–Minkowski space, we introduce a rotation index of the lines of curvature at the boundary umbilical point, which was developed by Choe [‘Sufficient conditions for constant mean curvature surfaces to be round’, Math. Ann. 323(1) (2002), 143–156]. Using the concept of the rotation index a...

Conformal Deformation of Spacelike Surfaces in Minkowski Space

We address the problem of second order conformal deformation of spacelike surfaces in compactified Minkowski 4-space. We explain the construction of the exterior differential system of conformal deformations and discuss its general and singular solutions. In particular, we show that isothermic surfaces are singular solutions of the system, which implies that a generic second order deformable su...

Caustics of de Sitter spacelike curves in Minkowski 3-space

In this paper, we consider evolutes of spacelike curves in de Sitter 2-space. Applying the theory of singularity theory, we find that these evolutes can be seen as one dimensional caustics which are locally diffeomorphic to lines or ordinary cusps. We establish the relationships between singularities of caustics and geometric invariants of curves under the action of the Lorentz group. c ©2016 A...

Spacelike Salkowski and anti-Salkowski Curves With a Spacelike Principal Normal in Minkowski 3-Space

A century ago, Salkowski [9] introduced a family of curves with constant curvature but non-constant torsion (Salkowski curves) and a family of curves with constant torsion but nonconstant curvature (anti-Salkowski curves). In this paper, we adapt definition of such curves to spacelike curves in Minkowski 3-space. Thereafter, we introduce an explicit parametrization of a spacelike Salkowski curv...

Ruled W - Surfaces in Minkowski 3 - Space

In this paper, we study a spacelike (timelike) ruled W-surface in Minkowski 3-space which satisfies nontrivial relation between elements of the set {K, KII , H, HII}, where (K,H) and (KII , HII) are the Gaussian and mean curvatures of the first and second fundamental forms, respectively. Finally, some examples are constructed and plotted.
