Abstract: | Let K be a field, k and n positive integers and let
matrices with coefficients in K. For any function there exists a unique solution
of the system of difference equations
defined by the matrix-k-tuple
such that
. The system
is called finite-memory system iff for every function g with finite support the values
are 0 for sufficiently big
. In the case
, these systems and the corresponding matrix-k-tuples have been studied in bis, fm, fmv, fv1, fv, fz. In this paper I generalize these results to an arbitrary positive integer k and to an arbitrary field K. |
