 regular curve
 A regular curve in a pseudo-Riemannian manifold is called a circle if it is an extrinsic sphere. We give an extension of the Fenchel-Borsuk result by introducing the total absolute torsion-curvature KT(γ) for regular curves γ whose tangent indicatrix is a piecewise regular curve (τ-closed curves). Every regular curve can be parametrized to have a constant speed but the parametrization is rarely known explicitly. The interpretation of the generalized Jacobian as a rigidificator for the Jacobian of a regular curve is not surprising (cf. Let D denote the interior of a piecewise regular curve of R2 having a point with Gauss curvature different from zero. 更多
