Abstract
|
We study the limit of first eigenfunctions of (discrete)
-Laplacian
on a finite subset of a graph with Dirichlet boundary condition, as
. We
prove that up to a subsequence, they converge to a summation of characteristic
functions of Cheeger cuts of the graph. We give an example to show that the limit
may not be a characteristic function of a single Cheeger cut.
