Summary: In this paper we give two representations of the solution of linear stochastic discrete-time systems in infinite-dimensional Hilbert spaces and we establish a relation between them. These representations are very important in order to obtain the characterizations of the uniform exponential stability and also to introduce and to characterize the notions of uniform observability and uniform controllability of the systems discussed.
