R02: Phase transport and complex structure

Purpose

The question addressed

R02 asks what scalar phase information determines about transport between comparisons, and what the smallest faithful real carrier of phase is.

Mathematical starting point

Objects and premises used

The phase functor of R01 on the path groupoid of a graph, with reciprocal phases on reversed edges.
The class of faithful continuous real linear representations of $U(1)$ .

Main results

What the paper establishes

Loop phase is the product of edge phases around a closed path; pure vertex-phase assignments have loop phase 1.
The minimal faithful real carrier is two-dimensional (Theorem R02.2).
Scalar phase records only part of the transport information; full transport can carry additional, noncommuting structure.

Theorem R02.2: The minimal phase plane

Result statement (summary)

Within the class of faithful continuous real linear representations of

U(1)

on finite-dimensional real vector spaces, the minimum real dimension is two, realised by the rotations

R(\theta)

. The element

J = R(\pi/2)

satisfies

J^2 = -I

and supplies a complex structure on the selected plane.

Assumptions and scope: The representation class is an explicit choice. The result concerns a mathematical phase carrier, not physical spatial dimension.

Explanation

Worked example: a triangle

Edge phases

z_{A\to B} = 1

,

z_{B\to C} = 1

and

z_{C\to A} = e^{i\pi/3}

give loop phase

e^{i\pi/3} \neq 1

.

Because the loop phase is not 1, no assignment of vertex angles can reproduce these edge phases. Loop phase is information that vertex differences alone cannot carry.

Physical interpretation and scope

What connects this to physics

The two-dimensional carrier is a mathematical phase plane. It is not a derivation of physical spatial dimension, and physical quantum states require further premises.

Historical background

PTG 1Historical background
An earlier closure architecture and phase manifold. The current account of phase composition and the minimal phase carrier is in R01 and R02.
PTG 2Related current treatment
Transport geometry and curvature are treated currently through loop phase in R02 and conditional carrier constructions in R07.
PTG IHistorical background
An early metric-free transport framework. Current phase transport is treated in R02.
PTG IIIHistorical background
Transport capacity and completeness relate to transport structure (R02) and conditional carrier constructions (R07).
QM IHistorical background
An early account of quantum mechanics from phase. The current treatment uses the phase plane (R02) and stated operational premises (R04).
