Dear Bruno,
I would like to start a new thread to discuss the nature and
existence of the many non computational things that you have
mentioned in your posts.
See my explanation of the phi_i to Liz. (on FOAR, I think). It is a
direct consequence of the existence of a universal machine.
I usually prove, in one (double) diagonalization that the predicate
TOTAL for the machine is not computable.
In fact most predicate *on* machine are not computable.
Could you find a few moments to write some remarks on these?
I can come back on this. perhaps when they are less posts! I intend to
explain first a bit of modal logic, but of course that computability
issue is important. But this is something I have already explained
more than once. Modal logic have only be explained one time, and a
very long time ago. I think that this is a bit more urgent. But don't
worry, we will spiral on computability again.
In particular I wonder if their proposed non-computability can be
expanded into disjoint classes such that we have some kind of
taxonomy of properties.
Well, yes. the degree of non computability is an entire branch of
mathematical logic.
Can they be represented approximately by a finite language?
You can axiomatize them in second order logic, or analysis.
Other than the restriction of recursive enumerability (modulo
homeomorphisms of their topological duals), what is it, in your
opinion, that makes such things non-computable?
Universality. That's a theorem. Its proof is very short (but needs
revision in elementary math). We will come back on it. I do explain
this in most of my papers (but perhaps too much concisely). Don't
hesitate to recall me on this if necessary.
Best,
Bruno
