Sensitivity to initial conditions

Click For Summary
SUMMARY

The discussion centers on the sensitivity to initial conditions in a dynamical system defined on a perfect metric space M = {x1, x2, x3, ...} U {p}, with a continuous function f mapping M to itself. The key question posed is whether this system exhibits sensitivity to initial conditions, defined as the existence of a distance d > 0 such that for any point x in M and any neighborhood V of x, there exists a point y in V and a positive integer n where the distance between f(n)(x) and f(n)(y) exceeds d. The implications of this definition are critical for understanding the behavior of dynamical systems.

PREREQUISITES
  • Understanding of perfect metric spaces

Let M = {x1, x2, x3, ...} U {p} be a perfect metric space.
Let f be continuous, taking M to M with f(xn) = xn+1 and f(p) = p.
I would like to know if this dynamical system is necessarily sensitive to initial conditions.

What do you mean by sensitive to initial conditions? How do you define it?
 
There exists d > 0, such that for each x in M and V a neighborhood of x there is y in V and a positive integer n with the property:
the distance between f(n)(x) ( the nth iterate of f) and f(n)(y) is > d.
