半空间上齐次函数空间中Hodge Laplacian的Hodge分解和极大分解

Hodge decompositions and maximal regularities for Hodge Laplacians in homogeneous function spaces on the half-space

Anatole Gaudin

摘要:

本文研究了全空间$\mathbb{R}^n$和半空间$\mathbb{R}^n_+$上任意阶微分形式在不同尺度的函数空间即齐次和非齐次Besov和Sobolev空间,$\dot{\mathrm{H}}^{s,p}$,$\dot{\mathrm{B}}^{s}_{p,q}$,${\mathrm{H}}^{s,p}$和${\mathrm{B}}^{s}_{p,q}$上的Hodge分解,对所有的$p\in(1,+\infty)$,$s\in(-1+\frac{1}{p},\frac{1}{p})$ . Hodge Laplacian算子的有界全纯泛函微积分和其他泛函分析性质也在半空间中进行了研究,并通过证明的Hodge分解对Hodge-Stokes算子和其他相关算子产生了类似的结果。作为后果,齐次算子和插值理论重温Danchin,Hieber,Mucha和Tolksdorf适用于齐次函数空间的边界条件,并导致各种最大的正则性结果与全球的时间估计,可以使用在流体动力学。此外,Hodge Laplacian和Hodge分解之间的联系甚至使我们能够在正则性指标$s\in(-1+\frac{1}{p},2+\frac{1}{p})$下,用附加的相容性条件来描述高阶Sobolev和Besov空间的Hodge分解。为了使所有这些性质在所需的函数空间的意义,我们也给出了适当的意义上的边界上的部分traces在附录中。La raison d '{ê}tre的这篇文章在于这样一个事实,即所选择的实现齐次函数空间是适合于非线性和边值问题,但需要一个仔细的方法来reprove结果已经道德上已知的。

英文摘要:

In this article, the Hodge decomposition for any degree of differential forms is investigated on the whole space $\mathbb{R}^n$ and the half-space $\mathbb{R}^n_+$ on different scale of function spaces namely homogeneous and inhomogeneous Besov and Sobolev space, $\dot{\mathrm{H}}^{s,p}$, $\dot{\mathrm{B}}^{s}_{p,q}$, ${\mathrm{H}}^{s,p}$ and ${\mathrm{B}}^{s}_{p,q}$, for all $p\in(1,+\infty)$ , $s\in(-1+\frac{1}{p},\frac{1}{p})$. The bounded holomorphic functional calculus, and other functional analytic properties, of Hodge Laplacians is also investigated in the half-space, and yields similar results for Hodge-Stokes and other related operators via the proven Hodge decomposition. As consequences, the homogeneous operator and interpolation theory revisited by Danchin, Hieber, Mucha and Tolksdorf is applied to homogeneous function spaces subject to boundary conditions and leads to various maximal regularity results with global-in-time estimates that could be of use in fluid dynamics. Moreover, the bond between the Hodge Laplacian and the Hodge decomposition will even enable us to state the Hodge decomposition for higher order Sobolev and Besov spaces with additional compatibility conditions, for regularity index $s\in(-1+\frac{1}{p},2+\frac{1}{p})$. In order to make sense of all those properties in desired function spaces, we also give appropriate meaning of partial traces on the boundary in the appendix.La raison d'{ê}tre of this paper lies in the fact that the chosen realization of homogeneous function spaces is suitable for non-linear and boundary value problems, but requires a careful approach to reprove results that are already morally known.
