AI总结:

本文研究系数可测且满足带Muckenhoupt $A_2$-权Gårding不等式的任意阶退化椭圆算子的Kato问题,推广已有工作,并解决 $p$ 接近 $2$ 时的非加权 $L^p$ 边值问题。

摘要:

我们考虑任意阶 $2m$($m\geq 1$)退化椭圆算子的Kato问题及其推广,其系数是可测的、复值的,并且关于Muckenhoupt $A_{2}$-权满足Gårding不等式;这推广了[Cruz-Uribe, Martell和Rios 2018]的工作。作为一个应用,当 $p$ 充分接近 $2$ 时,与这类算子相关的非加权 $L^{p}$-Dirichlet、正则性和Neumann边值问题得以解决。

英文摘要:

We consider the Kato problem and extensions for degenerate elliptic operators of arbitrary order $2m$ ($m\geq 1$), whose coefficients are measurable, complex-valued and satisfy the G$\mathring{a}$rding inequality with respect to a Muckenhoupt $A_{2}$-weight; this generalizes the work of [Cruz-Uribe, Martell and Rios 2018]. As an application, the unweighted $L^{p}$-Dirichlet, regularity and Neumann boundary value problems associated to such an operator are solved when $p$ is sufficiently close to $2.$
