VIII. Current research Interests
Currently, we are considering the family of generalized Lorenz chaotic system with the homoclinic orbit, heteroclinic orbit, bifurcation and other characteristics, in order to study the existence of Shil'nikov chaos and its formation mechanism in depth. Moreover，we also investigate application of chaos, such as control and anti-control, economic analysis, nonlinear current, biological and medical applications, and so on.
