We establish large deviation type estimates for i.i.d. products of two dimensional random matrices with finitely supported probability distribution. The estimates are stable under perturbations and require no irreducibility assumptions. In consequence, we obtain a uniform local modulus of continuity for the corresponding Lyapunov exponent regarded as a function of the support of the distribution. This in turn has consequences on the modulus of continuity of the integrated density of states and… 

Moduli of continuity for the Lyapunov exponents of random 𝐺𝐿(2)-cocycles

The Lyapunov exponents of i.i.d. random G L ( 2 ) \mathrm {GL}(2) -cocycles are Hölder continuous functions of the underlying probability distribution at each point with a simple

Upper bound on the regularity of the Lyapunov exponent for random products of matrices

We prove that if µ is a finitely supported measure on SL 2 ( R ) with positive Lyapunov exponent but not uniformly hyperbolic, then the Lyapunov exponent function is not α -H¨older around µ for any α

Hölder continuity of the Lyapunov exponents of linear cocycles over hyperbolic maps

Given a hyperbolic homeomorphism on a compact metric space, consider the space of linear cocycles over this base dynamics which are Hölder continuous and whose projective actions are partially

Parametric Furstenberg Theorem on Random Products of $SL(2, \mathbb{R})$ matrices.

We consider random products of $SL(2, \mathbb{R})$ matrices that depend on a parameter in a non-uniformly hyperbolic regime. We show that if the dependence on the parameter is monotone then almost

Quantitative lower bounds on the Lyapunov exponent from multivariate matrix inequalities

Lyapunov exponents characterize the asymptotic behavior of long matrix products. In this work we introduce a new technique that yields quantitative lower bounds on the top Lyapunov exponent in terms

A dynamical Thouless formula

Pseudo-gaps for random hopping models

For one-dimensional random Schrödinger operators, the integrated density of states is known to be given in terms of the (averaged) rotation number of the Prüfer phase dynamics. This paper develops a

A random cocycle with non Hölder Lyapunov exponent

We provide an example of a Schr\"odinger cocycle over a mixing Markov shift for which the integrated density of states has a very weak modulus of continuity, close to the log-H\"older lower bound

Moduli of continuity for the Lyapunov exponents of random 𝐺𝐿(2)-cocycles

The Lyapunov exponents of i.i.d. random G L ( 2 ) \mathrm {GL}(2) -cocycles are Hölder continuous functions of the underlying probability distribution at each point with a simple

Continuity of Lyapunov exponents for random two-dimensional matrices

The Lyapunov exponents of locally constant $\text{GL}(2,\mathbb{C})$ -cocycles over Bernoulli shifts vary continuously with the cocycle and the invariant probability measure.

Localization for the one-dimensional Anderson model via positivity and large deviations for the Lyapunov exponent

We provide a complete and self-contained proof of spectral and dynamical localization for the one-dimensional Anderson model, starting from the positivity of the Lyapunov exponent provided by

Effective perturbation theory for linear operators

We propose a new approach to the spectral theory of perturbed linear operators , in the case of a simple isolated eigenvalue. We obtain two kind of results: "radius bounds" which ensure perturbation

We give a new proof of E. Le Page’s theorem on the Hölder continuity of the first Lyapunov exponent in the class of irreducible Bernoulli cocycles. This suggests an algorithm to approximate the first

Large Deviations of the Lyapunov Exponent and Localization for the 1D Anderson Model

The proof of Anderson localization for the 1D Anderson model with arbitrary (e.g. Bernoulli) disorder, originally given by Carmona–Klein–Martinelli in 1987, is based in part on the multi-scale
