[Phys-L] Liouville Theorem, simple demostration

[Diego Saravia <dsa@unsa.edu.ar>]

Hi,
a long time ago I asked this group about a simple demostration of the
Liouville theorem

I received several answers and learned a lot.

But because the answers I received it seems to me that is not
a good idea.

Now I go arround the same question. And I think I have a simpler
demonstration..

I have two pdf, one in spanish, and other in english, translated by DeepL,
but the mathematics are not good in the translation.
I share both.

Thank you for any comment.
