Dispersion on certain Cartesian products of graphs

Kaïs Ammari, Mostafa Sabri

In this short note we prove a sharp dispersive estimate $∥ e^{i t H} f ∥_{\infty} < t^{- d /3} ∥ f ∥_{1}$ for any Cartesian product $Z^{d} □ G_{F}$ of th…

Dispersion for Schrödinger operators on regular trees

Kaïs Ammari, Mostafa Sabri

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 eac…
