Abstract

We consider the optimization problem of minimizing in the class of functions , with a constrain on the volume of . The conditions on the function allow for a different behavior at 0 and at . We consider a penalization problem, and we prove that for small values of the penalization parameter, the constrained volume is attained. In this way we prove that every solution is locally Lipschitz continuous and that the free boundary, , is smooth.
