On involutes of order k of a null Cartan curve in Minkowski spaces

Abstract: In this paper, we define an involute and an evolving involute of order k of a null Cartan curve in Minkowski space E n 1 for n ≥ 3 and 1 ≤ k ≤ n − 1. In relation to that, we prove that if a null Cartan helix has a null Cartan involute of order 1 or 2, then it is Bertrand null Cartan curve and its involute is its Bertrand mate curve. In particular, we show that Bertrand mate curve of Bertrand null Cartan curve can also be a non-null curve and find the relationship between the Cartan frame of a null Cartan curve… Show more

“…Such a situation does not exist in Euclidean case, straight lines do not have evolutes. The involute-evolute pairs of two spacelike curves, respectively, of a null curve and a spacelike curve, in four-dimensional Minkowski space were studied in [8], respectively, in [9], while the involutes of null Cartan curves in higher dimensions were analyzed in [10].…”
