Abstract:

The following result is proved: Let $M$ be a $n$-dimensional $C^1$-submanifold of $R^N$ which is domain of a given $\Lambda^n(R^N)$-valued map $\eta$ of class $C^1$. Then the subset of $M$ at points of which $\eta$ is nonzero, simple and tangent to $M$ is $C^2$ rectifiable. As a corollary we get a criterion for $C^2$-rectifiability of sets.
