$L^p$ norms and support of eigenfunctions on graphs
Résumé
This article is concerned with properties of delocalization for eigenfunctions of Schrödinger operators on large finite graphs. More specifically, we provide $L^p$-norm estimates for such eigenfunctions and show that they have a large support. Our estimates hold for any fixed, possibly irregular graph, in prescribed energy regions, and also for certain sequences of graphs such as N-lifts.
