具有粗糙和随机数据的Fourier-Lebesgue空间中薛定谔方程的收敛问题

Convergence problem of Schrödinger equation in Fourier-Lebesgue spaces with rough data and random data

Xiangqian Yan, Yajuan Zhao, Wei Yan

摘要:

本文考虑了薛定谔方程的收敛性问题。首先,我们证明了在Fourier-Lebesgue空间$\hat{H}^{\frac{1}{p},\frac{p}{2}}(\mathbb{R})(4\leq p<\infty),$ $\hat{H}^{\frac{3 s_{1}}{p},\frac{2p}{3}}(\mathbb{R}^2)(s_{1}>\frac{1}{3},3\leq p<\infty),$ $\hat{H}^{\frac{2 s_{1}}{p},p}(\mathbb{R}^n)(s_{1}>\frac{n}{2(n+1)},2\leq p<\infty,n\geq3)$中薛定谔方程在粗糙数据下的几乎处处点态收敛性.其次,我们证明了与一个薛定谔方程相关的极大函数估计在$\hat{H}^{s,\frac{p}{2}}(\mathbb{R})(s<\frac{1}{p})$数据下可能失效。最后,我们证明了薛定谔方程在$\hat{L}^{r}(\mathbb{R}^n)(2\leq r<\infty)$中具有随机数据的随机连续性.主要成分是引理2.4,2.5,3.2-3.4。

英文摘要:

In this paper, we consider the convergence problem of Schrödinger equation. Firstly, we show the almost everywhere pointwise convergence of Schrödinger equation in Fourier-Lebesgue spaces $\hat{H}^{\frac{1}{p},\frac{p}{2}}(\mathbb{R})(4\leq p<\infty),$ $\hat{H}^{\frac{3 s_{1}}{p},\frac{2p}{3}}(\mathbb{R}^2)(s_{1}>\frac{1}{3},3\leq p<\infty),$ $\hat{H}^{\frac{2 s_{1}}{p},p}(\mathbb{R}^n)(s_{1}>\frac{n}{2(n+1)},2\leq p<\infty,n\geq3)$ with rough data. Secondly, we show that the maximal function estimate related to one Schrödinger equation can fail with data in $\hat{H}^{s,\frac{p}{2}}(\mathbb{R})(s<\frac{1}{p})$. Finally, we show the stochastic continuity of Schrödinger equation with random data in $\hat{L}^{r}(\mathbb{R}^n)(2\leq r<\infty)$ almost surely. The main ingredients are Lemmas 2.4, 2.5, 3.2-3.4.
