Abstract
Theorems are proved on the existence and uniqueness of bounded and periodic solutions of a linear difference equation with operator coefficients in Banach space. For the stochastic analogue of the investigated equation, the existence and uniqueness are proved of solutions of a special form, periodic and stationary in the narrow sense.
