Lưu Trích dẫn Chia sẻAbstract
The linear difference system \(A_{n}x_{n+1}+B_{n}x_{n}=q_{n} (n\geq 0)\) is considered, where \(A_n, B_n \in \mathbb R^{m\times m}\) and \(q_n \in \mathbb R^m\) are given. It is assumed also that the singular matrices \(A_n\) have the same rank. The concept and properties of index-1 linear implicit difference system are investigated. Then the Floquet theorem on the representation of the fundamental matrix of index-1 periodic LIDS is established and the Lyapunov reduction theorem is proved. Some examples are discussed.
