Abstract:


Let (,ρ) and (,d) be two metric spaces such that (,d) is a complete length space with Alexandrov curvature bounded above, and (,ρ) is quasi homogeneous and admits a ball doubling measure μ, and a Dirichlet form b having both some additionnal properties. We prove that any mapping from into , which minimizes locally the Dirichlet - energy defined by μ, is α- Hölder - continuous outside a subset of of Hausdorff - codimension ≥2b, for any .
