Curves in 4-dimensional semi-rieamann spaces

CURVES IN 4-DIMENSIONAL SEMI-RIEAMANN SPACES This study consist of the five chapters. In section 1, introducation is given. In section 2, some information about the historical devolopment of IR^4 timelike pseudo-null space and fundamental definitions and theorems which are necessary are to be introduced in this study, respectively. In section 3, Bertrand curves of IR^4 timelike pseudo-null space and some properties of this spaces are reseached. In section 4, Helices of IR^4 timelike pseudo-null space are investigeted. In section 5, flows of curves in IR^4 semi-Rieamann spaces is illustrated.
