Hyper-Rössler (4D)

Rössler Hyperchaos (1979) — Otto Rössler's 4-dimensional extension of his attractor, with two positive Lyapunov exponents (hyperchaos). A hidden fourth coordinate w feeds back into y; the plot is the (x,y,z) projection.

dx/dt = −y − z
dy/dt = x + ay + w
dz/dt = b + xz
dw/dt = −cz + dw
