摘要
We give a complete characterization of those f : [0, 1] --> X (where X is a Banach space that has a Frechet smooth norm) that allow an equivalent C-2 - parameterization. For X = R, a characterization is well known. However, even in the case X = R-2, several quite new ideas are needed. Moreover, the very close case of parameterizations with a bounded second derivative is solved.
