Abstract
In this paper existence conditions and explicit expressions of bounded solutions for nonhomogeneous second-order difference systems defined in unbounded domains are given. Bounded solutions are expressed in ter ms of series involving a bounded fundamental matrix solution. Computab le approximate solutions are constructed and error bounds in terms of the data are given.
