外区域上的非自治Ornstein-Uhlenbeck方程

Non-autonomous Ornstein-Uhlenbeck equations in exterior domains

Tobias Hansel, Abdelaziz Rhandi

摘要:

本文考虑光滑外区域$Ω\subset \R^d$上的非自治Ornstein-Uhlenbeck算子在Dirichlet边界条件下的解.在适当的系数假设下,相应的非自治抛物柯西问题的解由一个关于$1< p < \infty$的$L^p(Ω)$的演化系统$\{P_Ω(t,s)\}_{0\leq s\leq t}$控制.进一步得到了空间导数的$L^p$ -估计和$P_Ω(t,s)$的$L^p$ - $L^q$光滑性质,即$0\leq s\leq t$.

英文摘要:

In this paper, we consider non-autonomous Ornstein-Uhlenbeck operators in smooth exterior domains $Ω\subset \R^d$ subject to Dirichlet boundary conditions. Under suitable assumptions on the coefficients, the solution of the corresponding non-autonomous parabolic Cauchy problem is governed by an evolution system $\{P_Ω(t,s)\}_{0\leq s\leq t}$ on $L^p(Ω)$ for $1< p < \infty$. Furthermore, $L^p$-estimates for spatial derivatives and $L^p$-$L^q$ smoothing properties of $P_Ω(t,s)$, $0\leq s\leq t$, are obtained.
