The `predictable' path of a swerving football and some peculiar features of the model equations
Subenoy Chakraborty, Jayanta K. Bhattacharjee · arXiv (Cornell University) · 2006
The motion of a spinning football brings forth the possible existence of a whole class of finite dynamical systems where there may be non-denumerably infinite number of fixed points. They defy the very traditional meaning of the fixed point that a point on the fixed point in the phase space should remain there forever, for, a fixed point can evolve as well! Under such considerations one can argue that a free-kicked football should be non-chaotic.
