No Null-Helix Mannheim Curves in the Minkowski Space E13 [PDF]
International Journal of Mathematics and Mathematical Sciences, 2011 We study a null Mannheim curve with time-like or space-like Mannheim partner curve in the Minkowski 3-space E13. We get the characterization of a null Mannheim curve.

Mannheim Curves in Nonflat 3-Dimensional Space Forms [PDF]
Advances in Mathematical Physics, 2015 We consider the Mannheim curves in nonflat 3-dimensional space forms (Riemannian or Lorentzian) and we give the concept of Mannheim curves. In addition, we investigate the properties of nonnull Mannheim curves and their partner curves.

On Mannheim partner curves in three dimensional Lie groups [PDF]
Miskolc Mathematical Notes, 2014 In this paper, we define Mannheim partner curves in a three dimensional Lie group G with a bi-invariant metric. And then the main result in this paper is given as (Theorem 3.3): A curve α with the Frenet apparatus {T,N,B,κ,τ} in G is a Mannheim partner curve if and only if λκ(1+H2)=1, where λ is constant and H is the harmonic curvature function of the ...

Some special curves belonging to Mannheim curves pair
Thermal Science, 2019 In this paper, we investigate special Smarandache curves with regard to Sabban frame for Mannheim partner curve spherical indicatrix. We create Sabban frame belonging to this curves. Smarandache curves are explained by taking position vector as Sabban vectors belonging to this curves.

Bertrand and Mannheim partner -curves on parallel surfaces
Boletim da Sociedade Paranaense de Matemática, 2017 In this paper we study Bertrand and Mannheim partner -curves on parallel surface. Using the definition of parallel surfaces, first we find images of two curves lying on two different surfaces and satisfying the conditions to be Bertrand partner -curve or Mannheim partner -curve. Then we obtain relationships between Bertrand and Mannheim partner -curves

A New Approach to Mannheim Curve in Euclidean 3-Space
Tamkang Journal of Mathematics, 2021 In this article, a new approach is given for Mannheim curves in 3-dimensional Euclidean space. Thanks to this approach, the necessary and sufficient conditions including the known results have been obtained for a curve to be Mannheim curve in E³.
