New characterization of D- focal curves in minkowski 3-space

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 3 1 2019 © Industrial Chemistry Research Institute. All Rights Reserved
