Lyapunov exponents in continuum Bernoulli-Anderson models
نویسندگان
چکیده
We study one-dimensional, continuum Bernoulli-Anderson models with general single-site potentials and prove positivity of the Lyapunov exponent away from a discrete set of critical energies. The proof is based on Fürstenberg’s Theorem. The set of critical energies is described explicitly in terms of the transmission and reflection coefficients for scattering at the single-site potential. In examples we discuss the asymptotic behavior of generalized eigenfunctions at critical energies. 1. The Main Result We study Anderson-type random Schrödinger operators

Lyapunov Exponents for Unitary Anderson Models
We study a unitary version of the one-dimensional Anderson model, given by a five diagonal deterministic unitary operator multiplicatively perturbed by a random phase matrix. We fully characterize positivity and vanishing of the Lyapunov exponent for this model throughout the spectrum and for arbitrary distributions of the random phases. This includes Bernoulli distributions, where in certain c...
متن کاملPositivity of Lyapunov exponents for Anderson-type models on two coupled strings
We study two models of Anderson-type random operators on two deterministically coupled continuous strings. Each model is associated with independent, identically distributed four-by-four symplectic transfer matrices, which describe the asymptotics of solutions. In each case we use a criterion by Gol’dsheid and Margulis (i.e. Zariski denseness of the group generated by the transfer matrices in t...

متن کاملPositivity of Lyapunov Exponents for a Continuous Matrix-valued Anderson Model
Abstract. We study a continuous matrix-valued Anderson-typemodel. Both leading Lyapunov exponents of this model are proved to be positive and distinct for all energies in (2,+∞) except those in a discrete set, which leads to absence of absolutely continuous spectrum in (2,+∞). This result is an improvement of a previous result with Stolz. The methods, based upon a result by Breuillard and Gelan...
متن کاملA Bernoulli Toral Linked Twist Map without Positive Lyapunov Exponents
The presence of positive Lyapunov exponents in a dynamical system is often taken to be equivalent to the chaotic behavior of that system. We construct a Bernoulli toral linked twist map which has positive Lyapunov exponents and local stable and unstable manifolds defined only on a set of measure zero. This is a deterministic dynamical system with the strongest stochastic property, yet it has po...
