Probabilistic Shadowing for Pseudotrajectories with Decreasing Errors
摘要
The shadowing property of pseudotrajectories with decreasing errors for a linear skew product is considered. The probabilistic properties of finite pseudotrajectories are studied. It is shown that for pseudotrajectories with errors decreasing exponentially, the typical dependence between the length of the pseudotrajectory and shadowing accuracy is polynomial. The proof is based on the large deviation principle and gambler’s ruin problem.
