摘要： We will present a thermodynamical formalism in order to give a multifractal analysis of weighted Birkhoff averages. The computation of multifractal spectrum leads us to give a study of Lyapounov exponent of infinite product of matrices. If the matrices are selected from a finite number of matrices and one of them is of rank 1 we get a closed formula for the Lyapounov exponent.
