Dispersive effects for the Schrödinger equation on finite metric graphs with infinite ends

Felix Ali Mehmeti, Kaïs Ammari, Serge Nicaise

AI总结:

该研究针对带无穷端点的有限度量图上的自由薛定谔方程,给出了$L^1$到$L^\ty$时间衰减率至少为$t^{-1/2}$的充分条件,并探究了有界子图与无界端点间的概率流动态。

摘要:

我们研究带无穷端点的有限度量图上的自由薛定谔方程,给出了获得至少为$t^{-1/2}$的$L^1$到$L^\ty$时间衰减率的充分条件。这些条件适用于某些带环和/或有界边长度可公度的度量图。此外,我们还研究了有界子图与无界端点之间的概率流动态。

英文摘要:

We study the free Schrödinger equation on finite metric graphs with infinite ends. We give sufficient conditions to obtain the $L^1$ to $L^\infty$ time decay rate at least $t^{-1/2}$. These conditions allow certain metric graphs with circles and/or with commensurable lengths of the bounded edges. Further we study the dynamics of the probability flow between the bounded sub-graph and the unbounded ends.
