Transfer matrices for Hermitian operators of higher dimensions
Christian Sadel (Santiago de Chile)
Abstract:
We show how a formula by Carmona for the spectral measure of a half line
Jacobi operator generalizes to general Hermitian operators of locally
finite hopping type. We use products of sets of rectangular, radial
transfer matrices for the spectral analysis. As corollaries we receive
criteria for proving a.c. spectrum. These criteria are applied to
certain models with disorder.
