On Mannheim partner curves in three dimensional Lie groups [PDF]

open access: yesMiskolc 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 ...

Spinor representation of framed Mannheim curves

open access: yesTurkish Journal of Mathematics, 2022
In this paper, we obtain spinor with two complex components representations of Mannheim curves of framed curves. Firstly, we give the spinor formulas of the frame corresponding to framed Mannheim curve. Later, we obtain the spinor formulas of the frame corresponding to framed Mannheim partner curve.

Some special curves belonging to Mannheim curves pair

open access: yesThermal 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

open access: yesBoletim 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
