R^n+1中二次位势薛定谔方程Kato型光滑估计的经典证明及应用

Classical Proofs Of Kato Type Smoothing Estimates for The Schrödinger Equation with Quadratic Potential in R^n+1 with application

Xuwen Chen

摘要:

利用Hermite函数技巧给出了R^n+1中具有二次位势的薛定谔方程的Kato型光滑估计的初等证明.这等价于证明一个奇异化Hermite投影核族的一致L^2(R ^n)到L^2(R^n)有界性。作为上述估计的一个应用,我们还证明了R^9塌缩变量型的Lahartz估计。

英文摘要:

This paper applies Hermite function techniques to give elementary proofs of Kato type smoothing estimates for the Schrödinger equation with quadratic potential in R^n+1. This is equivalent to proving a uniform L^2(R^n) to L^2(R^n) boundedness for a family of singularized Hermite projection kernels. As an applicationas the above estimate, we also prove the R^9 collapsing variable type Strichartz estimate.
