On focal curves of null Cartan curves


Abstract: The focal curve, which is determined as the locus of centers of osculatingpseudo-spheres of a null Cartan curve, is investigated in Minkowski(n+2)-space $\mathcal{M}^{n+2}.$ Moreover, a curve called \textit{accelerationfocal curve }of a null Cartan curve is introduced by using a new family of functions.

Keywords: Focal curve, null Cartan curve, vertex point, A-focal curve
