Abstract

Let \(f : U\subseteq \mathbb {R}^m\rightarrow \fancyscript{Q}_Q(\ell _2)\) be of Sobolev class \(W^{1,p}\), \(1 < p < \infty \). If \(f\) almost minimizes its \(p\) Dirichlet energy then \(f\) is Hölder continuous. If \(p=2\) and \(f\) is squeeze and squash stationary then \(f\) is in VMO.
