We consider a minimization problem that combines the Dirichlet energy with the nonlocal perimeter of a level set, namely with . We obtain regularity results for the minimizers and for their free boundaries using blow-up analysis. We will also give related results about density estimates, monotonicity formulas, Euler–Lagrange equations and extension problems.
