Null Bertrand partner D-curves on spacelike surfaces

Frontiers in Physics
In this paper, by using the Darboux frame of null curves, we define null Bertrand partner D-curves and present the relations between curvatures of these curves in Minkowski 3-space E13. In addition, we obtain some special results. Finally, by considering

Inextensible Flows of Curves on Lightlike Surfaces

Mathematics, 2018
In this paper, we study inextensible flows of a curve on a lightlike surface in Minkowski three-space and give a necessary and sufficient condition for inextensible flows of the curve as a partial differential equation involving the curvatures of the ...

On the curvatures of the ruled surfaces of b-lift curves

Cumhuriyet Science Journal, 2021
In this study, we defined a new curve which is called the B-Lift curve, also obtained the Frenet vectors of the B-Lift curve. The ruled surfaces have been produced by taking base curves B-Lift curves.

Construction of B-spline surface from cubic B-spline asymptotic quadrilateral

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
Asymptote is widely used in astronomy, mechanics, architecture and relevant subjects. In this paper, by analyzing the Frenet frame and the Darboux frame of a curve on the surface, the necessary and sufficient conditions for a quadrilateral boundary being
