A Study on Dual Mannheim Partner Curves
نویسندگان
چکیده
Mannheim partner curves are studied by Liu and Wang [3, 5]. Orbay and others extended the theory of the Mannheim curves to the ruled surface in Euclidean 3-space E3 [7]. We obtain the relationships between the curvatures and the torsions of the dual Mannheim partner curves with respect to each other. Mathematics Subject Classification: 53A04, 53A25, 53B40

No Null-Helix Mannheim Curves in the Minkowski Space E13
In the study of the fundamental theory and the characterizations of space curves, the related curves for which there exist corresponding relations between the curves are very interesting and important problems. The most fascinating examples of such curve are associated curves, the curves for which at the corresponding points of them one of the Frenet vectors of a curve coincides with the one of...
متن کاملMannheim Offsets of Ruled Surfaces
In a recent works Liu and Wang 2008; 2007 study the Mannheim partner curves in the three dimensional space. In this paper, we extend the theory of the Mannheim curves to ruled surfaces and define two ruled surfaces which are offset in the sense of Mannheim. It is shown that, every developable ruled surface have a Mannheim offset if and only if an equation should be satisfied between the geodesi...

متن کاملJ ul 1 99 3 LINEAR POTENTIALS AND GALACTIC ROTATION CURVES
We present a simple, closed form expression for the potential of an axisymmetric disk of stars interacting through gravitational potentials of the form V (r) = −β/r + γr/2, the potential associated with fundamental sources in the conformal invariant fourth order theory of gravity which has recently been advanced by Mannheim and Kazanas as a candidate alternative to the standard second order Ein...
