报告题目:Convergence problem of Schrödinger equation in Fourier-Lebesgue spaces with rough data and random data
报告摘要:In this talk, we consider the convergence problem of Schr\"odinger equation. Firstly,we show the almost everywhere pointwise convergence of Schr\"odinger equation in Fourier-Lebesgue spaces \hat{H}^{\frac{1}{p},\frac{p}{2}}(\R)(4\leqp<\infty),\hat{H}^{\frac{3s_{1}}{p},\frac{2p}{3}}(\R^{2})(s_{1}>\frac{1}{3},3\leqp<\infty),\hat{H}^{\frac{2s_{2}}{p},p}(\R^{n})(s_{2}>\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 dimensional Schr\"odinger equation can fail with data in \hat{H}^{s,\frac{p}{2}}(\R)(s<\frac{1}{p}). Finally, we show the stochastic continuity of Schr\"odingerequation with random data in \hat{L}^{r}(\R^{n})(2\leq r<\infty) almost surely. The main ingredients are Lemmas 2.4, 2.5, 3.2-3.4.
