New Characterization of D- Focal Curves in Minkowski 3-space

Abstract

In this paper, we study new D-focal curves in the Minkowski 3-space with Darboux frame. Moreover, we obtain some integral equations which they are characterizations for a space curve to be a D-focal curve. Finally, we give some characterizations about D-focal curves in the Minkowski 3-space M-1(3).
