Local estimates for conformal $Q$-curvature equations

Tianling Jin, Hui Yang

摘要:

本文给出了共形$Q$-曲率方程$$ (-Δ)^m u = K(x) u^{\frac{n+2m}{n-2m}} ~~~~~~ in ~ Ω\backslash Λ$$的正解在奇异集$Λ$附近的局部估计,其中$Ω\subset \mathbb{R}^n$是开集,$K(x)$是$Ω$上的正连续函数,$Λ$是$\mathbb{R}^n$的闭子集,$2 \leq m < n/2$和$m$是整数.在$K$在$Λ$上的临界点处满足一定平坦性条件下,证明了当$Λ$的上Minkowski维数小于$(n-2m)/2$时,$u(x) \leq C [{dist}(x, Λ)]^{-(n-2m)/2}$是平坦的.

英文摘要:

We derive local estimates of positive solutions to the conformal $Q$-curvature equation $$ (-Δ)^m u = K(x) u^{\frac{n+2m}{n-2m}} ~~~~~~ in ~ Ω\backslash Λ$$ near their singular set $Λ$, where $Ω\subset \mathbb{R}^n$ is an open set, $K(x)$ is a positive continuous function on $Ω$, $Λ$ is a closed subset of $\mathbb{R}^n$, $2 \leq m < n/2$ and $m$ is an integer. Under certain flatness conditions at critical points of $K$ on $Λ$, we prove that $u(x) \leq C [{dist}(x, Λ)]^{-(n-2m)/2}$ when the upper Minkowski dimension of $Λ$ is less than $(n-2m)/2$.
