Lancret-Type Results For A New Family Of Curves In Minkowski 3-Space, Héctor Guerrero Mora, Willy Sierra
Lancret-Type Results For A New Family Of Curves In Minkowski 3-Space, Héctor Guerrero Mora, Willy Sierra
Turkish Journal of Mathematics
In this article, using the concept of a Killing vector field along a curve, we extend certain results concerning a family of curves—previously studied in three-dimensional Euclidean space—to the setting of three-dimensional Minkowski space. Depending on the causal character of the curve, we derive Lancret-type results that establish the necessary and sufficient conditions for the existence of this family in three-dimensional Minkowski space. We determine the intrinsic equation of this family in three cases: (i) when the curve is nonnull with a nonnull acceleration vector, (ii) when the curve is spacelike with a null acceleration vector, and (iii) when the …
