Flexible polyhedra in the Minkowski 3-space [PDF]

manuscripta mathematica, 2001
Given a polyhedral surface, assume that it is prohibited to change the shape and size of any face but it is permissible to change the dihedral angles between the faces.

Biharmonic curves in Minkowski 3-space

International Journal of Mathematics and Mathematical Sciences, 2003
We give a differential geometric interpretation for the classification of biharmonic curves in semi‐Euclidean 3‐space due to Chen and Ishikawa (1991).

On Pseudohyperbolical Smarandache Curves in Minkowski 3-Space [PDF]

International Journal of Mathematics and Mathematical Sciences, 2013
We define pseudohyperbolical Smarandache curves according to the Sabban frame in Minkowski 3-space. We obtain the geodesic curvatures and the expression for the Sabban frame vectors of special pseudohyperbolic Smarandache curves.

Generalized Bertrand Curves in Minkowski 3-Space [PDF]

Mathematics, 2020
We define a generalized lightlike Bertrand curve pair and a generalized non-lightlike Bertrand curve pair, discuss their properties and prove the necessary and sufficient condition of a curve which is a generalized lightlike or a generalized non ...

A Note on Parametric Surfaces in Minkowski 3-Space [PDF]

The Scientific World Journal, 2014
With the help of the Frenet frame of a given pseudo null curve, a family of parametric surfaces is expressed as a linear combination of this frame. The necessary and sufficient conditions are examined for that curve to be an isoparametric and asymptotic ...

On Pseudospherical Smarandache Curves in Minkowski 3-Space

Journal of Applied Mathematics, 2014
In this paper we define nonnull and null pseudospherical Smarandache curves according to the Sabban frame of a spacelike curve lying on pseudosphere in Minkowski 3-space. We obtain the geodesic curvature and the expressions for the Sabban frame’s vectors

Isophote curves on timelike surfaces in Minkowski 3-space [PDF]

Annals of the Alexandru Ioan Cuza University - Mathematics, 2012
Isophote comprises a locus of the surface points whose normal vectors make a constant angle with a fixed vector. In this paper, isophote curves are studied on timelike surfaces in Minkowski 3-space E31.

The Geometry of Bezier Curves in Minkowski 3−Space

Universal Journal of Mathematics and Applications, 2023
The scope of this paper is to look at some aspects of the differential geometry of Bezier curves in Minkowski space. For that purpose, we firstly introduce Frenet Bezier curve in Minkowski 3-space.
