S-degenerate curves in Lorentz space

This thesis consists of three chapters?First chapter provides fundamental definitions and theorems related to Lorentz space/ null curves and second chapter related to s-degenerate curves.Third chapter first gives some definitions and theorems about rectifying curves in 4-dimensional Euclidean space. Then, our major contribution, characterizations when 2-degenerate curves becomes rectifying curves in the Lorentz space , is obtained in the second part. Note that a 2-degenerate curve is a special case of a s-degenerate curve.
