Abstract: | The paper deals with the problem of minimizing a free discontinuity functional under Dirichlet boundary conditions. An existence result was known so far for C1(∂Ω) boundary data û. We show here that the same result holds for û C0,μ(∂Ω) if
and it cannot be extended to cover the case
. The proof is based on some geometric measure theoretic properties, in part introduced here, which are proved a priori to hold for all the possible minimizers. |
