A NOTE ON SPRAYS OF ISOTROPIC CURVATURE
(Editura Bibliotheca-Bibliotheca Publ House, 2021)
A basic goal of this paper is to calculate, Weyl curvature of R-flat (Ricci-flat) spray of isotropic curvature and a locally projectively R-flat (Ricci-flat) spray, which is a projective invariance. Besides, the equivalents ...
On motion of robot end-effector using the curvature theory of timelike ruled surfaces with timelike directrix
(Universiti Putra Malaysia, 2014)
In this paper, we deal with the differential geometric properties of robot end-effector's motion by using the curvature theory of timelike ruled surfaces with timelike directrix.
THE RELATIONS BETWEEN NULL GEODESIC CURVES AND TIMELIKE RULED SURFACES IN DUAL LORENTZIAN SPACE D-1(3)
(Honam Mathematical Soc, 2019)
In this work, we study the conditions between null geodesic curves and timelike ruled surfaces in dual Lorentzian space. For this study, we establish a system of differential equations characterizing timelike ruled surfaces ...
Twisted surfaces with vanishing curvature in Galilean 3-space
(World Scientific Publ Co Pte Ltd, 2018)
In this work, we define twisted surfaces in Galilean 3-space. In order to construct these surfaces, a planar curve is subjected to two simultaneous rotations, possibly with different rotation speeds. The existence of ...
