Organizes thought or workflow but is not evidence for a physical claim. moves a structure between mathematical, physical or ordinary languages.
Exact assertion
A representation is a way for an abstract symmetry to act on a concrete list of states. The familiar example is rotating an arrow by multiplying its coordinate vector by a matrix. Furey's division-algebra constructions similarly organize particle-like states and ladder operations using complex numbers, quaternions and octonions.
The claim supplies a map or analogy. It becomes a derivation only after an explicit carrier-preserving map and invariant are given.
Chapter “The Furey interface”, section “What a representation does”. This is assertion 1 of 2 in that section.
Treat the passage as organization or analogy unless a cited carrier-preserving map is supplied.
moves a structure between mathematical, physical or ordinary languages.
Provide an explicit map that preserves the claimed structure, then identify an observable consequence that the analogy alone did not supply.
