Face 2-phase: how much overdetermination is enough to get symmetry in two-phase problems
Lorenzo Cavallina, Giorgio Poggesi
We provide a full characterization of multi-phase problems under a large class of overdetermined Serrin-type conditions. Our analysis includes both symmetry and asymmetry (includin…
