报告题目：On Cross-Dimensional Dynamic Systems
内容简介：Cross-dynamic systems have various of scientific and engineering backgrounds, such as insect population dynamics, spacecraft docking/undocking, power generator modeling, superstring, etc.
Under the semi-tensor product (STP, or MM-product) of matrices, the set of matrices (M) with arbitrary dimensions becomes a monoid (semi-group with identity). The set of vectors (V) with arbitrary dimensions is considered as the state space of cross-dimensional dynamic systems. The action of M on V is proposed as the MV-product, which satisfies the requirement of S-system. Define a (generalized) inner product on V, which provides a topological structure on $V$. Then the action becomes a cross-dimensional linear system. The following problems are discussed in this talk: (1) calculation of trajectories of cross-dimensional systems; (2) modeling of cross-dimensional control systems; (3) projection of a dynamic system of higher dimension onto a lower dimensional vector space; (4) some further topics.
