Let ν be the Furstenberg measure associated with a non-elementary probability measure μ on SL2(R). We show that, when μ has a finite second moment, the Fourier coefficients of ν tend to zero at infinity. In other words, ν is a Rajchman measure. This improves a recent result of Jialun Li. 

Random walks on SL_2(C): spectral gap and limit theorems

We obtain various new limit theorems for random walks on SL2(C) under low moment conditions. For non-elementary measures with a finite second moment we prove a Local Limit Theorem for the norm

Products of random matrices: a dynamical point of view

: We study products of random matrices in SL 2 ( C ) from the point of view of holomorphic dynamics. For non-elementary measures with finite first moment we obtain the exponential convergence towards

Fourier decay, Renewal theorem and Spectral gaps for random walks on split semisimple Lie groups

Let $\mu$ be a Borel probability measure on a split semisimple Lie group $G$, whose support generates a Zariski dense subgroup. Let $V$ be a finite-dimensional irreducible linear representation of

Random matrix products and measures on projective spaces

The asymptotic behavior of ‖XnXn−1…X1υ‖ is studied for independent matrix-valued random variablesXn. The main tool is the use of auxiliary measures in projective space and the study of markov

Kleinian Schottky groups, Patterson–Sullivan measures, and Fourier decay

Let $\Gamma$ be a Zariski dense Kleinian Schottky subgroup of PSL2(C). Let $\Lambda(\Gamma)$ be its limit set, endowed with a Patterson-Sullivan measure $\mu$ supported on $\Lambda(\Gamma)$. We show

Spectral gap properties for linear random walks and Pareto ’ s asymptotics for affine stochastic recursions

Let V = Rd be the Euclidean d-dimensional space, μ (resp. λ) a probability measure on the linear (resp. affine) group G = GL(V ) (resp. H = Aff(V )) and assume that μ is the projection of λ on G. We

Random Walks on Reductive Groups

We apply the previous results to random walks in products of algebraic reductive groups over local fields. We prove the Law of Large Numbers for both the Iwasawa cocycle and the Cartan projection. We

Dynamics of holomorphic correspondences

We generalize the notions of structural stability and hyperbolicity for the family of (multivalued) complex maps Hc(z) = z + c, where r > 1 is rational and zr = exp r log z. We discovered that Hc is

Fourier dimension and spectral gaps for hyperbolic surfaces

We obtain an essential spectral gap for a convex co-compact hyperbolic surface $${M=\Gamma\backslash\mathbb H^2}$$M=Γ\H2 which depends only on the dimension $${\delta}$$δ of the limit set. More
