ON 1-PARAMETER MOTION IN LORENTZ SPACE 3 1 E
Abstract
In this study, using Cayley Formula [1], A matrix-positive semi-orthogonal- is obtained from Darboux matrix [2] of α time-like curve. Taking c =α and by the equality
x = Ax0 + c , an one parameter H/H’ Lorentzian motion is specified. It is derived
Darboux vectors of this motion. And then the relation between Darboux matrices and curvature matrix is given. Moreover, it is shown α time-like curve must be a generalhelix on condition that components of Darboux vectors (matrices) are equal.
