Dominated Splittings and the Spectrum for Almost Periodic Jacobi Operators

Abstract

We prove that the resolvent set of any, possibly singular, quasi- periodic Jacobi operator is characterized as the set of all energies whose associated Jacobi cocycles induce a dominated splitting. This extends a well-known result by Johnson for Schrödinger operators.
