English abstract:
We formulate and analyze an adaptive non-conforming finite-element
method for the solution of convex variational problems. The class of
minimization problems we admit includes highly singular problems for
which no Euler-Lagrange equation (or inequality) is available. As a
consequence, our arguments only use the structure of the energy
functional. We are nevertheless able to prove convergence of an adaptive
algorithm, despite using refinement indicators which are not reliable
error indicators.
