Coarse Regularity of Solutions to a Nonlinear Sigma-model with~$L^p$~gravitino

Jürgen Jost, Ruijun Wu, Miaomiao Zhu

The regularity of weak solutions of a two-dimensional nonlinear sigma model with coarse gravitino is shown. Here the gravitino is only assumed to be in $L^p$ for some $p>4$. The pr…
