COMPTES RENDUS DE L ACADEMIE DES SCIENCES SERIE I-MATHEMATIQUE
We study the minimizers, in the class of convex functions, of an elliptic f
unctional with nonhomogeneous Dirichlet boundary conditions. We prove C-1 r
egularity of the minimizers under the assumption that the upper envelope of
admissible functions is C-1. This condition is optimal at least when the f
unctional depends only on the gradient [4].
We then extend this result to a problem without boundary conditions arising
in an economic model introduced by Rochet and Chone in [5]. (C) 2001 Acade
