## A new chaotic attractor coined.(English)Zbl 1063.34510

The authors deal with a new chaotic attractor generated by the following simple three-dimensional autonomous system $\dot x= a(y- x),\quad\dot y= -xz+ cy,\quad\dot z= xy- bz.\tag{1}$ Obviously, (1) is not diffeomorphic to the Lorenz and Chen system since the eigenvalue structures of their corresponding equilibrium points are not equivalent. It is straightforward but somewhat tedious to verify that there is no nonsingular coordinate transformation that can map one system into the other. Therefore, they are all not topologically equivalent.
