The delay Rosseler is
dx/dt=-y-z-a x(t-r),
dy/dt=x+by,
dz/dt=c+z (x-g),
this system has Chaotc attractor with a = 0.2, b =c = 0.2, g = 5.7, r = 2.0, and initial condition (0.1, 0.2, 0.3).
Is the next alternate representation of delay system in terms of N + 3 ordinary differential equations (ODEs) true or not?
dx1/dt= -xN+2 -xN+3 +a xN+1
dxi/dt= N(xi-1 – xi+1)/2r 2 ≤ i ≤ N
dxN+1/dt= N(xN – xN+1 )/r
dxN+2/dt=x1 + b xN+2
dxN+3/dt=c + xN+3 (x1 -g)
with initial conditions xi=0.1, 1 ≤ i ≤ N+1, xN+2 = 0.2, xN+3 =0.3.
