Local Geometric Properties Of The Lightlike Killing Magnetic Curves In De Sitter 3-Space

In this article, we mainly discuss the local differential geometrical properties of the lightlike Killing magnetic curve gamma(s) in S-1(3) with a magnetic field V. Here, a new Frenet frame {gamma, T, N, B} is established, and we obtain the local structure of gamma(s). Moreover, the singular properties of the binormal lightlike surface of the gamma(s) are given. Finally, an example is used to understand the main results of the paper.
