First-Order Logic TheoryTeoria em Lógica de Primeira Ordem
[Necessary condition]∀x (TransmitterHousing(x) → Assembly(x) ∧ ∃f (EnclosureFunction(f) ∧ bearerOf(x,f))) — Steps 1–3: genus + identity-giving function
[Function axiom: EnclosureFunction]∀f (EnclosureFunction(f) → ∀p (realizedIn(f,p) → EnclosureProcess(p)) ∧ ∃p (EnclosureProcess(p) ∧ realizedIn(f,p))) — Step 1: ∀ preserves type-type identity; ∃ rules out vacuous functions never realised
[Structural differentia (necessary only)]∀x (TransmitterHousing(x) → ∃hasComponentPartAtAllTimes.TransmitterElectronicCircuit) — Step 3: structural property — necessary condition, not sufficient (OWA prevents ≡)
[Necessary part: ?]∀x (TransmitterHousing(x) → ∃p (?(p) ∧ hasComponentPartAtAllTimes(x,p))) — Step 4: mereological commitment — every instance must have this part
[Process participation signature]∀x ∀f ((TransmitterHousing(x) ∧ EnclosureFunction(f) ∧ bearerOf(x,f)) →
∃m (FluidPortion(m) ∧ participatesIn(m,f)) ∧
∃e (InformationBearingArtifact(e) ∧ participatesIn(e,f)) ∧
processType(f,Containment)) — Step 5: typed participants in the realising process

The necessary conditions establish the core identity without risking false positives from other housing types that might share some structural features."@en ;
