Roughness of tempered exponential dichotomies for infinite-dimensional random difference equations (Q1949009)

The authors study the roughness of the tempered exponential dichotomies for linear random dynamical systems in Banach spaces. They prove the roughness without assuming their invertibility and the integrability condition of the multiplicative ergodic theorem. They give an explicit bound for the linear perturbation such that the dichotomy is persistent. They also obtain explicit forms for the exponent and the bound of the tempered exponential dichotomy of the perturbed random system in terms of the original ones and the perturbations.
