具有连续系数的散度型椭圆问题的病态解

Pathological solutions to elliptic problems in divergence form with continuous coefficients

Tianling Jin, Vladimir Maz'ya, Jean Van Schaftingen

摘要:

我们构造了一个函数$u \in W^{1,1}_{\mathrm{loc}} (B(0,1))$,它是$\Div (A \nabla u)=0$在分布意义下的解,其中$A$是连续的,而$u \not \in W^{1,p}_{\mathrm{loc}} (B(0,1))$是$p > 1$的解.我们还给出了一个函数$u \in W^{1,1}_{\mathrm{loc}} (B(0,1))$,使得对于每个$p < \infty$,$u$满足$\Div (A \nabla u)=0$,且$A$连续但$u \not \in W^{1, \infty}_{\mathrm{loc}}(B(0,1))$ .

英文摘要:

We construct a function $u \in W^{1,1}_{\mathrm{loc}} (B(0,1))$ which is a solution to $\Div (A \nabla u)=0$ in the sense of distributions, where $A$ is continuous and $u \not \in W^{1,p}_{\mathrm{loc}} (B(0,1))$ for $p > 1$. We also give a function $u \in W^{1,1}_{\mathrm{loc}} (B(0,1))$ such that $u \in W^{1,p}_{\mathrm{loc}}(B(0,1))$ for every $p < \infty$, $u$ satisfies $\Div (A \nabla u)=0$ with $A$ continuous but $u \not \in W^{1, \infty}_{\mathrm{loc}}(B(0,1))$.
