A Method of the Determination of a Geodesic Curve on Timelike Ruled Surface with Spacelike Rulings

چکیده
A curve which is called geodesic on a surface M in Lorentz 3-space is a special curve that its acceleration is everywhere normal to M. In this paper, we analyzed the non-linear differential equation to determine the geodesic curves on ruled surfaces which is obtained by a strictly connected spacelike straight line moving with Frenet’s frame along a timelike curve in . When we assume that curvature and torsion of base curve and components with respect to Frenet’s frame of spacelike straight-line are constants, for special integration constants, we show that the resulting non-linear differential equation can be integrated exactly. Finally, examples are given to show the geodesic curve on the timelike ruled surfaces with spacelike rulings.

A Method of the Determination of a Geodesic Curve on Ruled Surface with Time-like Rulings
A non-linear differential equation is analyzed to determine the geodesic curves on ruled surfaces with time-like rulings inR31. When it is assumed that curvature and torsion of the base curve and components with respect to Frenet’s frame of time-like straight-line are constants, for a special integration constant, it appears that the resulting non-linear differential equation can be integrated ...

متن کاملConstruction of a surface pencil with a common special surface curve
In this study, we introduce a new type of surface curves called $D$-type curve. This curve is defined by the property that the unit Darboux vector $vec{W}_{0} $ of a surface curve $vec{r}(s)$ and unit surface normal $vec{n} $ along the curve $vec{r}(s)$ satisfy the condition $leftlangle vec{n} ,vec{W}_{0} rightrangle =text{constant}$. We point out that a $D$-type curve is a geodesic curve or an...
