| Abstract: |
| We study the symmetry of solutions to a class of Monge-Ampère type equations in the domain outside a ball. By using a moving plane method and the transform introduced by Jian and Wang, we prove the radially symmetry of the solutions. |
| Key words: symmetry solution Monge-Ampère equation moving plane extreme principle |
