摘要：Dynamical systems are parts of the world,which can be seen as self-contained entities,with some temporal behavior,modeled with abstract mathematical systems. Such dynamical systems,defined by their states and dynamics,are the economic systems,and especially the financial ones. The behavior of these systems can be changed abruptly at certain critical values of underlying parameters. Close to a critical threshold the system becomes most sensitive,so tiny perturbations may trigger drastic changes. That’s why,in order to control a system we have to find such values of the parameters,that the state of the system became safe from being close to a critical threshold.
