In this paper, a chaotic system is investigated, which has only
three equilibria but exhibits a chaotic attractor for some
parameter values. The existence of heteroclinic orbits of
Shil'nikov type in the system is proved by using the undetermined
coefficient method. As a consequence, the Shil'nikov criterion
guarantees that the system has Smale horseshoes. Moreover, the
geometric structures of the chaotic attractor can be determined by
these heteroclinic orbits.
Key words:
chaos, heteroclinic orbits, Shil'nikov criterion
