Abstract

For a curve γ:IRn\boldsymbol{\gamma}:I\to\mathbb{R}^n of order n1n-1, we prove that the generalized curvatures κ1,,κn1\kappa_1, \ldots, \kappa_{n-1} can be expressed in terms of the leading principal minors of the matrix A(t)TA(t)\mathbf{A}(t)^T\mathbf{A}(t), where A(t)\mathbf{A}(t) is the n×nn\times n matrix whose ii-th column is γ(i)(t)\boldsymbol{\gamma}^{(i)}(t). This gives an efficient algorithm to calculate the curvatures.
