Stability of the Essential Spectrum of Second-Order Complex Elliptic Operators

open access: yes, 2007
We prove compactness of the resolvent difference for second order divergence form operators whose matrix functions are close enough at infinity. Our theorems include certain subelliptic cases as well as cases with unbounded coefficients.

Random Schrödinger operators arising from lattice gauge fields I: existence and examples

open access: yes, 1995
We consider models of random Schrodinger operators which exist thanks to a cohomological theorem in ergodic theory. Examples are ergodic Schrodinger operators with random magnetic fluxes on discrete two-dimensional lattices or non-periodic situations ...
