Global solutions of an obstacle-problem-like equation with two phases

• Concerning the obstacle-problem-like equation Deltau = lambda(+)\2 chi({u > 0})-lambda(-)/2chi({u < 0}), where lambda(+) > 0 and lambda(-) > 0, we give a complete characterization of all global two-phase solutions with quadratic growth both at 0 and infinity.
