散射流形上薛定谔方程解的奇性

Singularities of solutions to Schrodinger equation on scattering manifold

Kenichi Ito, Shu Nakamura

摘要:

本文研究了散射流形上薛定谔方程解的微局部奇性,具有渐近圆锥端点的非紧黎曼流形。在非捕获条件下,利用初始条件和经典散射映射刻画了解的波前集。我们的结果是密切相关的Hassell和Wunsch最近的工作,虽然我们的模型是更一般的方法,这在很大程度上依赖于散射理论的想法,是简单的,完全不同的。特别地,我们在标准的伪微分符号类中使用Egorov型参数,并避免使用Legendre分布。在证明中,我们采用了径向均匀波前集的微局部光滑性质,这比以前的结果更精确。

英文摘要:

In this paper we study microlocal singularities of solutions to Schrodinger equations on scattering manifolds, i.e., noncompact Riemannian manifolds with asymptotically conic ends. We characterize the wave front set of the solutions in terms of the initial condition and the classical scattering maps under the nontrapping condition. Our result is closely related to a recent work by Hassell and Wunsch, though our model is more general and the method, which relies heavily on scattering theoretical ideas, is simple and quite different. In particular, we use Egorov-type argument in the standard pseudodifferential symbol classes, and avoid using Legendre distributions. In the proof, we employ a microlocal smoothing property in terms of the radially homogenous wave front set, which is more precise than the preceding results.
