I believe it works only if the Lion and the tamer have a non null size (not represented as point). I am not sure of this, but if you represent the Lion and the tamer as points, the Lion can go as close as it want to the tamer, but never really reach him. Of course considering the tamer is on the border.

Nope, you're wrong.

Can you elaborate? I was wondering the same thing as yogsototh.

Basically there is nothing preventing the lion from reaching the tamers' coordinates exactly, i.e. it's not a case of the distance only closing "in the limit".

The paper linked elsewhere here gives an illustrative example where this happens in what is clearly finite time.

(This is if the tamer is on the border as parent claimed - the paper also shows that the lion can't win if he doesn't do this)
