DARBOUX FRAMES OF BERTRAND CURVES IN THE GALILEAN AND PSEUDO-GALILEAN SPACES
This paper aims to define and provide relationships between pairs of Bertrand curves on ruled surfaces of type I in the Galilean and pseudo-Galileanspaces.Moreover,someimportantconditionsbetween the curvatures of these curves are obtained. Finally, two examples are given to confirm our results.
Darboux frame, Bertrand curves, ruled surfaces, Galilean and pseudo-Galilean spaces.
