, 2021 In this paper, we deÖne a new type curve as V-Mannheim curve, V Mannheim partner curve and generating curve of Mannheim curve. We give characterization of these curve. In addition, we study a relation between Mannheim curve and spherical curve. Eventually, with Salkowski method, we give an example of the Mannheim curve.

Smarandache Curves of Mannheim Curve Couple According to Frenet Frame
Mathematical Sciences and Applications E-Notes, 2017 p>In this paper, when the unit Darboux vector of the partner curve of Mannheimnbsp;curve are taken as the position vectors, the curvature and the torsion of Smarandache curvenbsp;are calculated. These values are expressed depending upon the Mannheim curve. Besides,nbsp;we illustrate example of our main results./p>

Linear Potentials in Galaxy Halos by Asymmetric Wormholes
Universe, 2018 A spherically symmetric space-time solution for a diffusive two measures theory is studied. An asymmetric wormhole geometry is obtained where the metric coefficients has a linear term for galactic distances and the analysis of Mannheim and collaborators,

On generalized null Mannheim curves in E24
Mathematical Methods in the Applied Sciences, 2020 In the present paper, we introduce the notion of Cartan‐framed generalized null Mannheim curves in four‐dimensional semi‐Euclidean space with index 2, . We obtain the Cartan (or Frenet) frames and curvature functions of the generalized Mannheim mate curve by the help of curvature functions and Cartan frames of the generalized null Mannheim curve.

Mannheim B-curve couples in Minkowski 3-space
Tamkang Journal of Mathematics, 2020 In this paper, we define null Cartan 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 B-curves in terms of their Bishop curvatures.

Smarandache curves according to Sabban frame for Darboux vector of Mannheim partner curve [PDF]
AIP Conference Proceedings, 2017 In this paper, we investigated special Smarandache curves belonging to Sabban frame drawn on the surface of the sphere by Darboux vector of Mannheim partner curve. We created Sabban frame belonging to this curve. It was explained Smarandache curves position vector is consisted by Sabban vectors belonging to this curve.

Generalized Bertrand Curves of Non-Light-like Framed Curves in Lorentz–Minkowski 3-Space
MathematicsIn this paper, we define the generalized Bertrand curves of non-light-like framed curves in Lorentz–Minkowski 3-space; their study is essential for understanding many classical and modern physics problems.
