摘要
We consider the questions of existence and uniqueness of solutions of equation (0. 1) below. Under natural assumptions on Omega, mu and f, we show that the solutions u of (0. 1) are in one-to-one correspondence with the set of nonnegative harmonic functions h in Omega. The correspondence is given by M : u --> h, where h is the largest harmonic minorant of u in Omega.
