关于非自治$L^p$ -极大正则性的右乘扰动

On the right multiplicative perturbation of non-autonomous $L^p$-maximal regularity

Björn Augner, Birgit Jacob, Hafida Laasri

摘要:

本文研究非自治线性发展方程\begin{equation*}\label{Multi-pert1-diss-non} \dot u(t)+A(t)B(t)u(t)=f(t)\ \ t\in[0,T],\ \ u(0)=u_0. \end{equation*}的$L^p$ -极大正则性,其中$\{A(t),\ t\in [0,T]\}$是线性无界算子族,而算子$\{B(t),\ t\in [0,T]\}$是有界可逆的.在希尔伯特空间的情况下,我们考虑的运营商$A(t), \ t\in[0,T],$产生的半双线性型。所得结果应用于一维抛物型线性微分方程。

英文摘要:

This paper is devoted to the study of $L^p$-maximal regularity for non-autonomous linear evolution equations of the form \begin{equation*}\label{Multi-pert1-diss-non} \dot u(t)+A(t)B(t)u(t)=f(t)\ \ t\in[0,T],\ \ u(0)=u_0. \end{equation*} where $\{A(t),\ t\in [0,T]\}$ is a family of linear unbounded operators whereas the operators $\{B(t),\ t\in [0,T]\}$ are bounded and invertible. In the Hilbert space situation we consider operators $A(t), \ t\in[0,T],$ which arise from sesquilinear forms. The obtained results are applied to parabolic linear differential equations in one spatial dimension.
