摘要

This paper preeents the problem of generating four-wing(eight-wing)chaotic attractors.The adopted method consists in suitably coupling two(three)identical Lorenz systems.In analogy with the original Lorenz system,where the two wings of the butterfly attractor are located around the two equilibria with the unstable pair of complex-conjugate eigenvalues,this paper shows that the four wings(eight wings)of these novel attractors are located around the four (eight)equilibria with two(three)pairs of unstable complex-conjugate eigenvalues.
