A random cocycle with non Hölder Lyapunov exponent
Pedro Duarte, Silvius Klein, Manuel Santos
We provide an example of a Schrödinger cocycle over a mixing Markov shift for which the integrated density of states has a very weak modulus of continuity, close to the log-Hölder…

Large deviations for products of random two dimensional matrices
Pedro Duarte, Silvius Klein
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…
