SPACELIKE AND TIMELIKE NORMAL CURVES IN MINKOWSKI SPACE-TIMEKazim Ilarslan and Emilija NesovicKirikkale University, Faculty of Sciences and Arts, Department of Mathematics, Kirikkale, Turkey and University of Kragujevac, Faculty of Science, Department of Mathematics and Informatics,34000 Kragujevac, SerbiaAbstract: We define normal curves in Minkowski space-time $E^4_1$. In particular, we characterize the spacelike normal curves in $E^4_1$ whose Frenet frame contains only non-null vector fields, as well as the timelike normal curves in $E^4_1$, in terms of their curvature functions. Moreover, we obtain an explicit equation of such normal curves with constant curvatures. Keywords: Minkowski space-time, normal curve, curvature Classification (MSC2000): 53C50; 53C40 Full text of the article: (for faster download, first choose a mirror)
