Mark Pollicott (Warwick University): Computing the Lyapunov exponent for random matrix products

Abstract. Given two square matrices A and B, the Lypanuov exponent (associated to a Bernoulli measure) is the average growth rate of n-fold products of these matrices.   In the case of positive matrices, we describe a method for getting formal expressions for the exponents, which leads to a useful method of appoximating them numerically.
