Ovidiu Savin

摘要:

考虑退化的$$\det D^2 u= f \quad \{in $\Om$}, \quad \quad f \sim \, d_{\p \Om}^α\quad \{near $\p \Om$,}$$型Monge-Ampere方程,其中$d_{\p \Om}$表示到区域边界的距离,$\Om$和$α>0$是正幂.我们在自然条件下的边界数据和右侧的边界处获得了$C^2$估计。J.X. Hong,G. Huang和W.王.

英文摘要:

We consider degenerate Monge-Ampere equations of the type $$\det D^2 u= f \quad \{in $\Om$}, \quad \quad f \sim \, d_{\p \Om}^α\quad \{near $\p \Om$,}$$ where $d_{\p \Om}$ represents the distance to the boundary of the domain $\Om$ and $α>0$ is a positive power. We obtain $C^2$ estimates at the boundary under natural conditions on the boundary data and the right hand side. Similar estimates in two dimensions were obtained by J.X. Hong, G. Huang and W. Wang.
