On Timelike Bertrand Curves In Minkowski 3-Space
(Honam Mathematical Soc, 2016)
In this paper, we study the timelike Bertrand curves in Minkowski 3-space. Since the principal normal vector of a timelike curve is spacelike, the Bertrand mate curve of this curve can be a timelike curve, a spacelike curve ...
New Types of Canal Surfaces in Minkowski 3-Space
(Springer Basel Ag, 2016)
Canal surface is a surface formed as the envelope of a family of spheres whose centers lie on a space curve. In Minkowski 3-space, many authors studied canal surfaces. However, when one investigates the papers, it is obvious ...
A new approach to Bertrand curves in Euclidean 3-space
(SPRINGER BASEL AG, 2020)
In this article, a new approach is given for Bertrand curves in 3-dimensional Euclidean space. According to this approach, the necessary and sufficient conditions including the known results have been obtained for a curve ...
Mannheim B-Curve Couples In Minkowski 3-Space
(TAMKANG UNIV, 2020)
In this paper, we define null Cartan Mannheim and pseudo null Mannheim curves in Minkowski 3-space according to their Bishop frames. We obtain the necessary and the sufficient conditions for pseudo null curves to be Mannheim ...
On generalized null Mannheim curves in E24
(WILEY, 2021)
In the present paper, we introduce the notion of Cartan-framed generalized null Mannheim curves in four-dimensional semi-Euclidean space with index 2, E24. We obtain the Cartan (or Frenet) frames and curvature functions ...
Some Characterizations Of Generalized Null Mannheim Curves In Semi-Euclidean Space
(INST BIOPHYSICS & BIOMEDICAL ENGINEERING, BULGARIAN ACAD SCIENCES, 2020)
In the present paper, we investigate Cartan framed generalized null Mannheim curves in the four-dimensional semi-Euclidean space of index two. We construct the Cartan (or Frenet) frames and curvature functions of generalized ...
Generalized Null Bertrand Curves In Minkowski Space-Time
(Univ Al I Cuza, Fac Math, 2014)
COKEN and CIFTCI proved that a null Cartan curve in Minkowski space-time E-1(4) is a null Bertrand curve if and only if k(2) is nonzero constant and k(3) is zero. That is, the null curve with non-zero curvature k(3) is not ...
Characterizations of timelike slant helices in Minkowski 3-space
(Univ Osijek, Dept Mathematics, 2014)
In this paper, we investigate the tangent indicatrix, the principal normal indicatrix and the binormal indicatrix of a timelike curve in Minkowski 3-space E-1(3) and we construct their Frenet equations and curvature ...
On the Involute-Evolute of the Pseudonull Curve in Minkowski 3-Space
(Hindawi Publishing Corporation, 2013)
We have generalized the involute and evolute curves of the pseudonull curves alpha in E-1(3); that is, alpha is a spacelike curve with a null principal normal. Firstly, we have shown that there is no involute of the ...
Some characterizations of null osculating curves in the Minkowski space-time
(Estonian Academy Publishers, 2012)
In this paper we give the necessary and sufficient conditions for null curves in E-1(4), to be osculating curves in terms of their curvature functions. In particular, we obtain some relations between null normal curves and ...
