Some toy model calculations
I. 1 + 1 string spacetime slice, neglecting Weyl conformal dilation but
including energy and momentum translation generators i.e. A00 = Energy
Generator, A11 = Linear Momentum Generator in sense of Noether's theorem
relating symmetries to conservation laws for continuous groups. We mean
appropriate matrix representations of the Lie algebra depending on what
physical vector space they operate on, e.g. Cartan mobile tetrad local
frames of reference for gravity and internal vector spaces for "charges"
of U(1), SU(2) & SU(3).

The geometrodynamic gauge-covariant partial derivatives acting on
Tuv(source) matter fields are

,u --- ;u = ,u + (Connection)u^a^bAab

(use ' for base space indices)

;0' = ,0' + (Connection)0'^0^0A00 + (Connection)0'^1^1A11

+ (Connection)0'^1^0A10 + (Connection)0'^0^1A01

A01 = - A10 = space-time Lorentz boost

;0' = ,0' + (Connection)0'^0^0(Energy) + (Connection)0'^1^1(Linear
Momentum)

+ [(Connection)0'^1^0 - (Connection)0'^0^1]A10

;0' = ,0' + (LC Connection)0'^0^0(Energy) + (LC Connection)0'^1^1(Linear
Momentum)

+ (Tensor Torsion Field)0'^1^0(Lorentz Boost)

Note how the String Torsion Field is the Yang-Mills "Phase" of the
Lorentz Boost.

The Equivalence Principle is encoded in the (LC Connection) terms.

Similarly for ;1

The tetrads tilt in infinitesimal displacements as:

ea(x + dx) = eb(x)(Connection at x)u^badx^u

e0(x + dx) = [(Connection at x)0'^00dx^0' + (Connection at
x)1'^00dx^1']e0(x)

+ [(Connection at x)0'^10dx^0' + (Connection at x)1'^10dx^1']e1(x)

e1(x + dx) = [(Connection at x)0'^01dx^0' + (Connection at
x)1'^01dx^1']e0(x)

+ [(Connection at x)0'^11dx^0' + (Connection at x)1'^11dx^1']e1(x)

II 2 + 1 slice for anyonic vacuum ODLRO fractional charge/quantum
statistics "World Hologram Plate"

cc* + c*ce^i(Anyonic Phase) = 1

Anyonic Phase = 0 2D fermions

Anyonic Phase = pi 2D bosons

Control Anyonic Phase with perpendicular magnetic field on a 2D nano
quantum well showing fractional quantum Hall effect.



Exotic matter effects are neither fermion nor boson.

What does that do to the spin-statistics connection?

Flux tubes pin to charged fermions. Effective charges are fractional
like quarks, but only in 2D + 1 space-time "surfaces". In world
holography there are no dynamically independent volume degrees of
freedom for the geometrodynamic field, hence the Bekenstein bound for
black hole thermodynamics and the amount of bits that can be packed into
a Volume V ~ V^2/3/Lp^2 ~ (/\Lp^2)^-1 for our pocket universe on the
cosmic landscape of parallel universes.

,u --- ;u = ,u + (Connection)u^a^bAab

(Connection)0'^2^2A22

Similarly for ;1'

Note that in Einstein's 1916 theory, TORSION = 0, therefore the Lorentz
boost and rotation terms vanish!

Homework, do this for 3D + 1.

Bottom Line
Gravity is "More is different" emergent from the Standard Model of
quarks & leptons with gauge bosons. Standard quantum gravity theories
are not even wrong, i.e. loop quantum gravity, string theory, canonical
quantization are like trying to quantize elasticity theory.

This is the 11th dimension so to speak. 10 from the Poincare group.
From the principle fiber bundle

M(Base Space) = Cartan Mobile Tetrad Frame Fiber Bundle/(Poincare Group
+ Weyl Dilation)

dimM = 11?

This is intuitive - still thinking about it - non-rigorous.

That is, 4 translations of the tetrad local frame, 3 rotations, 3 boosts
+ 1 Weyl dilation. Each parameter "phase" "angle of rotation" is a
"dimension" of M.

11 G-Orbit equivalence classes partition of the tetrad bundle.

G = Poincare Group + Weyl Dilation

Also an addition 4 special conformal transformations not accounted for

Dear Jack :

Also in Weyl's geometry the non-metricity tensor Q is
zero as well.

The Weyl covariant derivative of the metric is zero.
Despite that the lengths of vectors change under
parallel transport (in Weyl spacetime )
the angle of two vectors remains the same ( conformal
property ) under paralell transport.

Best wishes
