Novel four-wing and eight-wing attractors using coupled chaotic Lorenz systems

This paper presents the problem of generating four-wing (eight-wing)chaotic attractors. The adopted method consists in suitably couplingtwo (three) identical Lorenz systems. In analogy with the originalLorenz system, where the two wings of the butterfly attractor arelocated around the two equilibria with the unstable pair ofcomplex-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 unstablecomplex-conjugate eigenvalues.
