摘要
引进了变参数离散动力系统的生成子、弱生成子的概念,证明了变参数离散动力系统有生成子当且仅当它有弱生成子,并且研究了变参数离散动力系统的生成子的其它性质,从而扩展了变参数离散动力系统的研究范围.
Given the definition of generator and weak generator for variable-parametric discrete dynamical system. The fact that the variable-parametric discrete dynamical system has generator if and only if it has weak generator was proved, and studied other properties of generator. These results further extend the scope of the research on variable-parametric discrete dynamical system.
