薛定谔方程的半经典奇性传播性质

Semiclassical Singularity Propagation Property for Schrödinger Equations

Shu Nakamura

摘要:

考虑变系数的薛定谔方程,假定它是$R^n$上平坦拉普拉斯算子的长程扰动.我们用初态刻画了薛定谔方程解的波前集。然后,它表明,奇异性传播的经典流,它是制定在一个半经典设置。方法类似于远程散射理论,特别是一个修改的自由传播,采用。

英文摘要:

We consider Schrödinger equations with variable coefficients, and it is supposed to be a long-range type perturbation of the flat Laplacian on $R^n$. We characterize the wave front set of solutions to Schrödinger equations in terms of the initial state. Then it is shown that the singularity propagates following the classical flow, and it is formulated in a semiclassical settings. Methods analogous to the long-range scattering theory, in particular a modified free propagator, are employed.
