Multiple valued maps into a separable Hilbert space that almost minimize their Dirichlet energy or are squeeze and squash stationary
arXiv:1402.3232
Abstract
Let $f : U\subset\Rm \to \calQ_Q(\ell_2)$ be of Sobolev class , . If almost minimizes its Dirichlet energy then is Hölder continuous. If and is squeeze and squash stationary then is in VMO.
