WebMay 28, 2024 · We prove upper bounds on the $L^p$ norms of eigenfunctions of the discrete Laplacian on regular graphs. We then apply these ideas to study the $L^p$ … WebConsider a random d -regular graph on n vertices. What can be said about its nontrivial (i.e. orthogonal to the constant) eigenfunctions? For example, I'm interested whether there …
WebAbstract. We prove a quantum-ergodicity theorem on large graphs, for eigenfunctions of Schrödinger operators in a very general setting. We consider a sequence of finite graphs endowed with discrete Schrödinger operators, assumed to have a local weak limit. We assume that our graphs have few short loops, in other words that the limit model is ... WebJun 13, 2024 · We conclude this section with an example of graphs in which eigenfunctions localize on small regions, justifying why we exclude certain eigenvalues of the …
WebI'll discuss ways to construct realistic "landscape functions" for eigenfunctions ψ of quantum graphs. This term refers to functions that are easier to calculate than exact … WebThis suggests a notion of \graph with boundary" and what their adjacency matrices should be. All the standard comparison theorems about eigenvalues of the Laplacian and nodal regions of eigenfunctions of the Laplacian carry over verbatim to graphs. In particular there is a precise graph analogue of the fact that when Dirichlet eigenfuctions
WebSep 19, 2024 · We give a delocalization estimate for eigenfunctions of the discrete Laplacian on large (d+1)-regular graphs, showing that any subset of the graph …

The underlying philosophy (which is made precise later in the paper) is that we can continue such a planar graph to a tessellation with non-positive corner curvature after generously removing the set of positive curvature. can i use ground almonds instead of flourWebgraph Laplacian eigenfunctions constructed on a certain type of trees, which we pre-viously observed through our numerical experiments. The eigenvalue distribution for such a tree is a smooth bell-shaped curve starting from the eigenvalue 0 up to 4. Then, at the eigenvalue 4, there is a sudden jump.
