It was conjectured that ifsatisfieseverywhere in, thenfcan be uniformly approximated by-mappingsgsatisfyingeverywhere. While in general, there are counterexamples to this conjecture, we prove that the answer is in the positive when. More precisely, if, our result yields an almost-uniform approximation of locally Lipschitz mappings, satisfyinga.e., by-mappingsgwith, providedis simply connected. The construction of the approximation employs techniques of analysis on metric spaces, including the theory of metric trees (-trees).
