内容摘要Abstract: 

  The Lyapounov exponent of random product of non-negative matrices exists almost surely by Furstenberg-Kesten theorem or Kingman theorem. But both Furstenberg-Kesten theorem and Kingman theorem tell us nothing about a given sample of matrices. We find conditions to ensure the existence of Lyapounov exponent for EVERY generic choice of matrices. If one of matrices from which we select our matrices is of rank one, we find a closed formula for the Lyapounov exponent.
