Hi Brian,
I was wondering if you could connect (in the paper) the maths with our
universe? As an example. What set operations or structures correspond to
the standard particle model entities, what constitutes a chemical
reaction or energy, what space is made of...
I believe I have a working candidate for a plausibility case for a
structure being literally the universe, assuming the MUH.
It is the structure U(U), where the first U is script and the second
is blackboard bold, on page 3 of the following document, listed under
conjecture 4.
I was skimming though a book by Roberto Cignoli, Itala D'Ottaviano, and
Daniele Mundici called Algebraic Foundations of Many-Valued Reasoning.
Recall that I conjectured that the Physicist's universe has an
MV-algebra structure. I probably should have said that the Physicist's
universe is the
Dear Brian,
have you had a look at Universal logic?
http://en.wikipedia.org/wiki/Universal_logic
Maybe there are points of interest in there for you (the wikipedia
article is only a stub, but contains some names to google).
Cheers,
Günther

Great reference, thanks!
I'm investigating a problem I can phrase two ways, given that the
category of MV-algebras is equivalent to the category of lattice-ordered
Abelian groups with a distinguished strong unit.
So one way to phrase my question, and I'm guess it has been answered
before

So, about your question, I've actually never heard
of a lattice-ordered abelian group, so I don't think I
can help you there. I can tell you about the
connection of category theory to

I think we have no choice in the matter (once we assume the

structure among others. The physical emerged from a sort of sum
pertaining on the whole of the mathematical possible histories. If this
