PROBLEM: Distribution of Eigenvalue Spacings for Band Diagonal Matrices
INVESTIGATOR: Nathan Miller
DESCRIPTION: The purpose of this paper is to look at the nearest
neighbor spacings of
eigenvalues for band-diagonal matrices. We study the cases when the matrix
elements are determined
using a Cauchy distribution, a Laplace (double exponential) distribution, and
a Uniform distribution.
When a band of radius 1, i.e. a diagonal matrix, is used, the spacings of
eigenvalues should look very
differently than when the spacings of eigenvalues for a band of radius N (of
an N by N matrix),
i.e. just a random symmetric N by N matrix, is used.
