Abstract:

We consider the following integral functional with nearly-linear growth $\int_{\Omega} Du \log(1+ Du ) \ dx$ where $u:\ \Omega \subset \Bbb R^{n} \rightarrow \Bbb R^{N}, n\ge 2, \ N\geq 1$ and we prove that any local minimizer $u$ has locally H\"older continuous gradient in the interior of $\Omega$ thus excluding the presence of singular sets in $\Omega$. This functional has recently been considered by several authors in connection with variational models for problems from the theory of plasticity with logarithmic hardening. We also give extensions of this result to more general cases.
