Özet
© 2017, Sciendo. All rights reserved.In the present paper, we define the notions of Lorentzian Sabban frames and de Sitter evolutes of the unit speed space-like curves on de Sitter 2-space (formula presented). In addition, we investigate the invariants and geometric properties of these curves. Afterwards, we show that space-like Bertrand curves and time-like Bertrand curves can be constructed from unit speed space-like curves on de Sitter 2-space (formula presented) and hyperbolic space ℍ2, respectively. We obtain the relations between Bertrand curves and helices. Also we show that pseudo-spherical Darboux images of Bertrand curves are equal to pseudo-spherical evolutes in Minkowski 3-space (formula presented). Moreover we investigate the relations between Bertrand curves and space-like constant slope surfaces in (formula presented). Finally, we give some examples to illustrate our main results.
