Abstract

In this paper the existence of a polynomial approximation of input-output maps for distributed systems is proved. The result is achieved for a class of mappings uniformly continuous with respect to a suitable topology on bounded sets of input space. The causality structure is preserved in the approximating polynomial. As an example of the theory, the distributed linear perturbed system is considered.
