A multiplicative ergodic theorem in random and simultaneous dynamics

In this manuscript, we consider finitely many maps defined on a compact probability space; each of which preserves the probability measure.

We consider two aspects of growth of dynamical systems in this scenario; the first setting where we let some infinite lettered word determine the path through which the orbit of points evolve, while the second setting where we consider all possible paths through which the orbit of a set may evolve.

Our aim in this paper is to provide a full description of the celebrated multiplicative ergodic theorem, originally due to Oseledets, for such dynamical systems that is point-valued (as in the first case) and set-valued (as in the second case).
