Curvature via the de Sitter’s Space-Time

Sarajevo Journal of Mathematics
We define the central curvature and the total central curvature of a closed curve in a Lorentz $(n + 1)$--space. In addition, we obtain estimates for the total central curvatures of spacelike pure polygons. The study is done by using the n-dimensional de
