摘要：

Some overdetermined problems associated to monotone elliptic quasilinear operators are investigated. A model operator is the p-Laplacian. Assuming that a solution exists, the domain of our problem is shown to be either a ball centered at the origin or an annulus centered at the origin. In the special case of the Laplace equation, a result of approximate radial symmetry is also obtained. Proofs are based on comparisons with radial solutions.
