摘要:

在给定$2\leq p<\infty$,$s\in (0, 1)$和$t\in (1, 2s)$的条件下,建立了\[ \int_Ω \int_Ω K\left (x,|x-y|,\frac{x-y}{|x-y|}\right ) \frac{(u(x)-u(y))(φ(x)-φ(y))}{|x-y|^{n+2s}} dx dy = g[φ], \quad \forall ϕ\in C_c^{\infty}(Ω) \]型非局部方程解的$W^{t,p}$ Calderon-Zygmund内估计,其中$Ω\subset \mathbb{R}^{n}$是开集.这里我们假设$K$是有界的、非负的并且在第一个条目中是连续的--并且通过假设$K$在锥中是严格正的来确保椭圆性。设置的选择,使它适用于非局部方程的流形,但结构的方程是足够的一般,它也适用于某些分数$p$拉普拉斯方程周围的点,其中$u \in C^1$和$|\nabla u| \neq 0$。

英文摘要:

Given $2\leq p<\infty$, $s\in (0, 1)$ and $t\in (1, 2s)$, we establish interior $W^{t,p}$ Calderon-Zygmund estimates for solutions of nonlocal equations of the form \[ \int_Ω \int_Ω K\left (x,|x-y|,\frac{x-y}{|x-y|}\right ) \frac{(u(x)-u(y))(φ(x)-φ(y))}{|x-y|^{n+2s}} dx dy = g[φ], \quad \forall ϕ\in C_c^{\infty}(Ω) \] where $Ω\subset \mathbb{R}^{n}$ is an open set. Here we assume $K$ is bounded, nonnegative and continuous in the first entry -- and ellipticity is ensured by assuming that $K$ is strictly positive in a cone. The setup is chosen so that it is applicable for nonlocal equations on manifolds, but the structure of the equation is general enough that it also applies to the certain fractional $p$-Laplace equations around points where $u \in C^1$ and $|\nabla u| \neq 0$.
