Summary: [For the entire collection see Zbl 0527.00041.]
It is demonstrated how the spaces \(V^*\) and \(V^-\), known in the geometric theory of linear systems can be generalized to systems over rings and how one can check whether these spaces have the feedback property. Based on these results, the solution of the disturbance- rejection problem is given, with and without internal stability.
