System which escapes infinitely often

127 Views Asked by At

Is there a system of ordinary differential equations (over the reals) of the form

$$ \begin{align} \dot{x}(t) &= f(x(t)) \\ x(0) &= x_0 \end{align} $$

with the following properties:

  • $f(0) = 0$
  • $f$ is continuously differentiable everywhere
  • $f$ does not have any singularities (implied by the second property)
  • $x(t)$ has infinitly many singularities

For example, the system

$$ \begin{align} \dot{x}(t) &= x(t)^2 \\ x(0) &= 1 \end{align} $$

satisfies the first three properties but its solution is

$$ x(t) = \frac{1}{1 - t} $$

so it has only one singularity at $t = 1$ and so it fails the fourth property.

Another example (taken from the comment of Lutz Lehmann) is the system

$$ \begin{align} \dot{x}(t) &= x(t)^2 + 1 \\ x(0) &= 0 \end{align} $$

which satisfies the last three properties as its solution

$$ x(t) = \tan(t) $$

has infinitley many singularities, namely $\frac{\pi}{2}(2 k + 1)$ for $k \in \mathbb{Z}$. However, it fails the first property because $f(0) \neq 0$ (in fact the system has no equilibrium at all).

Is there a system with the above properties which has solutions with infinitely many singularities?
