Dear Matti,

Focusing on two notions...

It is logical entailment or implication that "goes backwards" with

respect to time. This is discussed at length in Pratt's paper ratmech.ps

If we take the negation: "not A <--- not B", we are just reversing the

respective arrows. Umm, only in the strict binary boolean case is ~~A =

A, so it gets a bit complicated when we are using a Chu_[0,1] space to

represent the interactions of a given pair of LSs, since fuzzification

allows for ~A \intersect A =/= 0 under certain conditions!

Yes, but I am trying to discuss how the ordering by inclusion is

constructed. If we just assume that the ordering is a priori, then we do

not have to deal with the question as to why the selves (or more

generally, observations) are ordered as they are. It is this assumption

that exists in the classical model of space-time and is in severe

contradiction with facts, such as those illustrated in the EPR and

delayed choice situations.

We can just say that temporal orderings are given by the MNP of the

quantum jumps, but I am trying to understand the details better. I think

of this as asking what decides the winner in a tournament; while we can

not say with certainty 1 who will win. All we can do is to set up

"pay-off matrixes", etc.

*

I think that a situation is required such that a "large enough"

sampling of the possible actions of the selves can be had so that a

winner can be reasonably predicted. We see an example of this in

political elections in a democratic country. The individual electorate

(representing the individual subselves) vote and a sample of these are

polled by the media to form a statistical sample of the whole and this

sample is used to predict the outcome "sooner than the actual counting

of the ballots can occur". I think that the situation involved with

"selves" is a continuous voting/polling situation since the "elections"

occur at every quantum jump!

The p-adic prime looks to me to well model the size of the sample

population!

I say that since the determination of the particular experience is not

modelable locally, as it involves an entire light-like hypersurface, the

causality not considered as an experience itself. Only the results of

the determination enter into the "picture". So I agree this you here. My

only question is in the nature of the "absoluteness" of the minima of

the Kaehler action. Umm, what are the quantities involved in the Kaehler

action? Is there an associated Lagrangian or Hamiltonian? What

"information measures" are related to it?

*

Since we have many observers, it is natural to consider that there are

many observational experiences to be considered. The notion of a single

objective reality only makes sense IFF the class of observables is

strictly sharp (binary certainty). The problem I see is that only a

prediction can be made up to the accuracy allowed by the p-ary cut-off

(\epsilon of accuracy). So the smearing of "reality" that QM predict is

no surprise!

Sure! Invariance structures are defined by geometry, so a physics = a

geometry.

Next I would like to better understand the problem you have with

Frieden's work...

Onward!
