Consider a general 3D system like:
x' = f1(x,y,z)
y' = f2(x,y,z)
z' = f3(x,y,z)
Can we predefine f1, f2 and f3 in such a way that if there is any strange attractor, it will have some certain topological properties, like its place and shape?
However, here I don't mean the type of strange attractor (Lorenz like, Chen like, … or number of scrolls). I want to design a chaotic system which is for example around a specific curve (like a circle) in the 3D space.
