Null Cartan Bertrand curves of AW(k)-type in Minkowski 4-space

This Letter considers the curvature conditions of AW(k)-type (k=1,2,3)(k=1,2,3) null Cartan curves, and investigates null Cartan Bertrand curves. We show that null Cartan Bertrand curves are AW(k)-type (k=1,2,3)(k=1,2,3) curves in Minkowski 4-space.

► We provide the type of AW(k) null curves.
► We give the curvature conditions of null Cartan curves of AW(k)-type.
► Null Cartan Bertrand curves are AW(k) curves.
