渐近欧氏散射中的半经典估计

Semiclassical estimates in asymptotically Euclidean scattering

Andras Vasy, Maciej Zworski

摘要:

本文给出了渐近欧氏流形上拉普拉斯算子的非捕获长程扰动的半经典预解估计。我们的证明是基于一个积极的换向器参数,不同的换向器类型的估计也积极。预解估计,包括加权的索伯列夫空间的估计,是一个直接的后果。

英文摘要:

In this note we obtain semiclassical resolvent estimates for non-trapping long range perturbations of the Laplacian on asymptotically Euclidean manifolds. Our proof is based on a positive commutator argument which differs from Mourre-type estimates by making the commutant also positive. The resolvent estimates, including the weighting of the Sobolev spaces in the estimates, are an immediate consequence.
