Dynamic feedback (A,B)-invariant submodules for linear systems over commutative Noetherian domains Original Research Article

In this paper, some basic characterizations of (A,B)-invariant submodules for linear systems over commutative Noetherian domains are studied. First, a notion of dynamic feedback (A,B)-invariant submodules for such systems is introduced, and then it is shown that this notion is equivalent to (A,B)-invariance.
