We prove a Γ -convergence result for an energy functional related to some fractional powers of the Laplacian operator, (− Δ) s for 1/2 < s < 1, with two singular perturbations, that leads to a two-phase problem. The case (− Δ) 1/2 was considered by Alberti–Bouchitté–Seppecher in relation to a model in capillarity with line ...
