正则树上Schr dinger算子的色散

Dispersion for Schrödinger operators on regular trees

Kaïs Ammari, Mostafa Sabri

摘要:

我们证明了两个模型的色散估计:离散正则树上的邻接矩阵,和度量正则树上的薛定谔方程,每个边/顶点上具有相同的潜力。后一个模型可以被认为是周期薛定谔算子在实数线上的情况的扩展。我们建立了一个$t^{-3/2}$衰减这两个模型是尖锐的,因为我们给一阶渐近。

英文摘要:

We prove dispersive estimates for two models~: the adjacency matrix on a discrete regular tree, and the Schrödinger equation on a metric regular tree with the same potential on each edge/vertex. The latter model can be thought of as an extension of the case of periodic Schrödinger operators on the real line. We establish a $t^{-3/2}$-decay for both models which is sharp, as we give the first-order asymptotics.
