Abstract
In this study, it is investigated that the Schur stable difference equation systems $y(n+k)=Cy(n)$ under which perturbations remains Schur stable. Some continuity theorems of the first order systems in the literature are re-expressed for the $k-th$ order system $y(n+k)=Cy(n)$. All the results obtained are also supplemented by numerical examples.
