与锥点区域相关的闭线性算子的生成型不等式

Generation type inequalities for closed linear operators related to domains with conical points

A. Favaron

摘要:

设${\cal A}(x;D_x)$是二阶线性微分算子的散度型.证明了当${\rm Re}ł$足够大且${\cal A}(x;D_x)$的定义域由一类与$\rsp^n$的锥开有界集$n \ge 1$有关的加权Sobolev函数空间构成时,算子$łI- {\cal A}(x;D_x)$($ł\in\csp$和$I$代表恒等算子)是闭的内射的.

英文摘要:

Let ${\cal A}(x;D_x)$ be a second-order linear differential operator in divergence form. We prove that the operator $łI- {\cal A}(x;D_x)$, where $ł\in\csp$ and $I$ stands for the identity operator, is closed and injective when ${\rm Re}ł$ is large enough and the domain of ${\cal A}(x;D_x)$ consists of a special class of weighted Sobolev function spaces related to conical open bounded sets of $\rsp^n$, $n \ge 1$.
