Lyapunov Exponents For Some Quasi-Periodic Cocycles
We consider SL(2,R)-valued cocycles over rotations of the circle and prove that they are likely to have Lyapunov exponents ≈ ± logλ if the norms of all of the matrices are ≈ λ. This is proved for λ sufficiently large. The ubiquity of elliptic behavior is also observed. Consider an area preserving diffeomorphism f of a compact surface. Assume that f is not uniformly hyperbolic, but that it has o...
متن کاملStochastic Stability of Lyapunov Exponents and Oseledets Splittings for Semi-invertible Matrix Cocycles
We establish (i) stability of Lyapunov exponents and (ii) convergence in probability of Oseledets spaces for semi-invertible matrix cocycles, subjected to small random perturbations. The first part extends results of Ledrappier and Young [18] to the semiinvertible setting. The second part relies on the study of evolution of subspaces in the Grassmannian, where the analysis developed, based on h...
متن کاملHölder continuity of Oseledets splittings for semi-invertible operator cocycles
For Hölder continuous cocycles over an invertible, Lipschitz base, we establish the Hölder continuity of Oseledets subspaces on compact sets of arbitrarily large measure. This extends a result of Araújo et al [On Hölder-continuity of Oseledets subspaces J. Lond. Math. Soc. 93 (2016) 194–218] by considering possibly non-invertible cocycles, which, in addition, may take values in the space of com...
متن کاملAlmost periodic Szego cocycles with uniformly positive Lyapunov exponents
We exhibit examples of almost periodic Verblunsky coefficients for which Herman’s subharmonicity argument applies and yields that the associated Lyapunov exponents are uniformly bounded away from zero. As an immediate consequence of this result, we obtain examples of almost periodic Verblunsky coefficients for which the associated probability measure on the unit circle is pure point.
متن کاملProperties of Lyapunov Exponents for Quasiperodic Cocycles with Singularities
We consider the quasi-periodic cocycles (ω, A(x, E)) : (x, v) 7→ (x+ω, A(x, E)v) with ω Diophantine. Let M2(C) be a normed space endowed with the matrix norm, whose elements are the 2 × 2 matrices. Assume that A : T × E → M2(C) is jointly continuous, depends analytically on x ∈ T and is Hölder continuous in E ∈ E , where E is a compact metric space and T is the torus. We prove that if two Lyapu...
