| Abstract: |
| Pinching-estimate is an important method for studying the convexity of the solutions. It is known that the Pinching-estimate is important in Geometry, and we apply it into partial differiatial equations. In this paper, we mainly give the Pinching-estimates for some semilinear second order elliptic equations and fully nonlinear elliptic equations. |
