Chen

Chen Attractor — Discovered by Guanrong Chen in 1999, this system was found as a dual of the Lorenz system in a specific mathematical sense. It exhibits chaotic behavior with a distinctive two-scroll structure that differs from both the Lorenz and Rössler attractors.

dx/dt = a(y − x)
dy/dt = (c − a)x − xz + cy
dz/dt = xy − bz
