This "parallel transport" notion is what Weyl made a careful analysis
of in his work and why he reasoned that Riemannian geometry needed to be
generalized! But, Weyl did not consider the possibility that multiple
space-times are needed to model multiple observers. He assumed, as do
most, that there is only one M^4 and its related fields/connections for
all...
Parallel transport is the conceptual tool to model motions of the
"shadows", but fact is that that which is projecting the shadows is not
a "ONE" in the ontological sense, it is the "MANY" possible finite
subsets of U. They project onto each other...
This is a very important point that becomes obvious in a discussion
about the difference between "actual" and "potential" infinities... What
is ontologically a priori is the Universe, which is an "Actual"
infinity, thus it is ONE. The dynamics of the shadows are "potential"
infinities, thus are "MANY", thus the uncertainty formalism that Hitoshi
has discovered and discussed in his papers connects the time of the LS
to its measure of uncertainty.
The idea that the Universe, as a "static, pre-given entity" is
non-dynamical is part of my thinking and that of Hitoshi and,
appearently yours. Michael C. Mackey also addresses this notion in his
book Time's Arrow with his "God Theorem"... The key notion that we all
seem to agree on is that the "parts" can have dynamical behavior (are
not at equilibrium) while the "whole" is static. The notion of time is
given in the manner that the parts, by interacting among themselves,
evolve toward equilibrium, e.g. evolve toward isomorphism with the
whole: the "Union with All" of mystics. But the key notion is that this
process literally takes forever to accomplish!

The argument about "a priori orderings" that I have been trying to
communicate since the beginning of the Time List relates to this! The
Oneness aspect of the Universe is forever out of reach since it is
Everything simultaneously. It would have at least a multiple connected
topology - everything mapping isomorphically to everything else... I am
proposing that the subsets of U are simply-connected manifolds, up to
isomorphism in the classical limit of hbar = zero.
Here is a crude sketch of my idea about the applicability of Weyl's
geometry:
"The necessary and sufficient condition that a Weyl geometry may be
reduced to a Riemannian geometry is that a vector keep its original
length after transplantation along an arbitrary closed trajectory.
Indeed, the condition of such a length preservation is ...
(15.40) \surface integral_C of dl/l = \surface integral_C \PHI_\alpha
dx^\alpha = 0
[forgive my terrible ascii]
and it is well known that \PHI_\alpha|\beta - PHI_\beta|\alpha
\equivalent 0 is the necessary and sufficient condition for the
integrability requirement of (15.41) in simply connected regions."
[from Introduction to General Relativity by Adler, Bazin and Schiffer,
1975. pg. 496]
These "simply-connected regions" would have properties that are
represented by Maxwell field equations. These define the patterns of
causal connections that M^4's represent. They have the appearance of
being unique from the point of view of an observer O because they are
the framing within which an observation by O is possible. If we consider
for the sake of illustration the ability to observe this projection
process "from a divine point of view" we would see that each O (an LS)
has its own M^4 constructed piece by piece by mappings between its
internal propagator's (quantum mechanical) dynamic's configuration space
and points in the manifold W.
What is difficult to grasp is that the "points" that make up W are the
possible exteriors as centers of mass ("cm"). In other words, the
"exteriors" of LS are ontologically different from the "interiors"! The
former are facets of the "MANY" and thus appear "classical" while the
latter are finite facets of the "ONE" and are quantum mechanical! The
ONE and the MANY are co-inductive aspects of the Universe, they define
each other, but the "meaning" of such definition is only possible for CE
reasons as being "in time" and since each LS, as a unique facet of U,
has its own time and gauge scale, it constructs its own local consistent
"reality".

Umm, I fail to see how it is necessary and sufficient to require that
spinoral properties be aspects of the ONE. I see them as constructed
dynamically in the act of observation in that they are aspect of the
framing. Thus I do not see them as a priori givens! Is it not enough to
show that the "shadow" is a construction of the mapping between LSs? Do
we really have to suppose that the "statue" exists "out there" prior to
the sculptor's work?! It "exists" only in the sense of being a
possibility! The metric or related properties are given by the act of
observation which is determined by the local logical entailment aspect
of the informorphism that is the interaction between LSs.
To be sure, I need to discuss the "compactness" notion that you
mentioned before with regards to the W(r)...

Umm, I an missing something! :-( I say that each LS observes a
classical like world, thus can be approximated and modeled by classical
math, but we need to consider co-induction, not just classical
induction... Perhaps I am misunderstanding you!

Sure, the particular symmetries "fix the metric", but I argue that this
fixing is a computational act, not an a priori synthetic! This is
metaphorically similar to the situation of a new-born baby; it has the
potential to become many different adults, what determines the actual
adult it becomes depends on both its interactions with the world
constrained by the consistency requirements of the world determined by
others that are interacting wherein. The World is not a priori given in
an ontological sense, it is co-indictively defined by the interactions
of its members, it is the intersection of its member's possibilities
that define it!
The way that M^4s are constructed "piece-by-piece" is well illustrated
in Penrose's discussion of quasi-crystals and it highlighted in by
Forbidden Symmetry paper:

But how do we derive particular actual properties by merely evoking the
fact that they exist? Existence is "outside of time", it is tenseless.
The dynamics that define sharp properties only occur "in time", in fact,
I propose that in a subtle sense, they ARE time, but since each LS has
its own unique dynamics (defined by its internal QM propagator), each
has their own time and thus their own length scale or gauge. Thus I say
that each LS constructs its space-time M^4 framings by interaction with
other LSs.
The Cauchy problem holds in the static case since the Uncertainty
principle prohibits the a priori definite "sharp" properties! It is for
this reason that Einstein was very opposed to QM! His statement "GOD
does not play with dice" [to determine the properties of the world]
speaks directly to this!

I say that observations are co-inductively related posets of points (as
an abstraction since true infinitesimal points can not be distiguised
from each other as they can not encode any information!!!), not
individual points per say. To call them "space-time framings" speaks to
the fact that we always make observations in terms of a M^4 frame... The
quantum jumps are more epiphenomena that objective, but the restriction
that observers can only communicate effectively about M^4 framings that
do not logically contradict each other follows from CE! The
schizophrenic is an example of an observer that is attempting to
communicate about a M^4 framing that is logically inconsistent with
another's!

I see the evolution of information in terms of the evolution of the LSs
as they interact. Thus the act of the Universe 'experiencing itself' is
an ongoing process. It is what "concurrent computation" is all about is
a fundamental sense! Again, this is why I find Peter's work so useful!

Could you give me the reference of this paper? I can order a copy from
the library! :-) The loss of "general coordinate invariance" does not
bother me at all, in fact, I say that it is an illusion that results
from the fact that LSs can not communicate if they have different
histories. I say: LSs can interact only to the degree that their
histories are not inconsistent with each other. If the think of the LS's
histories in terms of M^4s, we see that to be consistent is for there be
isomorphisms between at least one point and that the "Hamming distance"
between points in the the Powersets of the LSs observations is
equivalent to the degree of mutual consistency or "agreement" between
the LSs.

Yes, but here the error is in the tacit (subconscious) assumption that
the psychological time of one person is one and the same of that of
another! The clocking by the QM propagator of the LS defines the
individual time of the LS, thus representing psychological time very
well!
The "everything has not already happened" notion is indeed related to
psychological time, but in the sense stated above. "Everything" much
included all possible "actual" experiences, and obviously, these involve
NP-complete computational issues! This later notion is at the heart of
my argument.

I am not communicating my notion since your are not aware of the
NP-completeness problem! Karl Svozil's papers point the way! We agree
that "there can be *no first quantum jump*"! The ideas of co-induction
and related issues involved are in Peter's papers...

The notion of "gradual statistical increase of p-adic prime of the
universe" is given in my thinking in the sense that the overall
concurrent interactions of LSs are modelable in this way. It would be a
representation of the accumulated "experience of the Universe", but with
the caveat that it is information that can not be gotten in finite time
or finite energy with arbitrary accuracy. The operator formalisms that
Schommers talks about, I believe, is useful to us in thinking about
this!

In a way, yes. You are a Platonist, and I something different. I think
that Plato's Idea Reality *is* the Universe in-itself, but as Kant
argued well, is not knowable in-itself. I see it as Existence itself!
All experiences, measurements, observations, qualia or what ever, are
not given directly by their mere existence (as all exist in the
ontological sense), but have finite properties given by the interactions
between the finite subsets or "facets" or LSs of the Universe. We can
only observe shadow, consciousness is not capable of knowling the
"in-itself"!

How could this be? The very definition of such requires the a priori
computation of the causal structure of such a space-time! Newton et al,
assumed that God did this "in the beginning" and thus they give us a
"clock-work" paradigm of the world. I am speaking to a paradigm that is
more like a network of CGI (computer graphic interface) that is
constructed by the very act of interaction, thus the "means" of
communicating between LSs is given simultaneously with the "ability" to
communicate! There is no "absolute" ex nihilo beginning and no absolute
pre-defined causal ordering and thus no pre-given M^4!
I am trying to model this by using a generalization of Weyl's ideas...

Is there any relationship between "zero modes" and "null geodesics"?

Does this implicitly assume a unique set of measuring "tools" for all
possible observers? If so, how? I am very aware that the usual
explanation involves the notion that numbers "exist" a priori, but,
really, how can it be affirmed that something is knowable just by
postulating its existence? CE does not imply necessity of knowledge or
experienciability! In order to allow for the uniqueness of the
individual self, it is necessary and sufficient that there is at least
one attribute that can be unique to such. The mere CE postulate is not
enough, we need a dynamical difference. When one posits a pre-given
metric for all and assumes that all observer exist *in* the same space,
it is the postulation of a prison for the self from which there is no
escape.

This seems to follow from Hitoshi's theory...

Sure, I can agree with that. Each person's sensory experiences can be
explained a unique integration of many almost disjoint quantum
measurements, thus I think of posets... But what is troubling me is the
notion that the localization is somehow independent of what it is that
makes the poset different for each person. I think that if we start out
with the notion that each measurement is informative only in comparison
to some aspect of the measuring device, here a person, we could perhaps
avoid the trap of classically. The idea of a pre-existing classical
world or space-time in which all observers are "embedded" is the error,
but it is very hard to escape it! It must be done. We need a radical
shift in paradigm!

Again, I fail to see how you propose to claim that a unique M^4_+ xCp_2
*is* the TOTALITY OF EXISTENCE! These are definite actual properties and
as such can only be given within the context of particular experiences!
The Universe in itself can only *exist* by CE reasoning, the
construction of M^4_+ xCP_2 is a subjective projection; it is phenomena,
not noumena, e.g. I believe that the particular patterns of behavior
that is called "physics" is derived from observation, it is not priori
to it. This is the case presented by Frieden!
Is is the "behavioral form" that the "shadows" take that is given by
the interactions between the finite facets of the Universe. All we can
observe is the shadows and the "wall" upon which they think that they
are "projected" is just the Powerset of the set or equivalence class of
"shadows".
Again we are merely debating the semantics of our perspective model of
our worlds, and thus it is the usefulness of our notions that matters in
the long run... :-)

I agree with this only in the sense that all possible quantum histories
"exists", but the "ordering" of them, that makes consciousness "flow" is
not a priori! This is the basis of the computation argument!
