prime splits in ℤ[ω] iff p ≡ 1 (mod 3)
Theorem.prime splits in ℤ[ω] iff p ≡ 1 (mod 3) — p = a²−ab+b² (the x²+3y² form) iff p≡1 mod 3 or p=3 (ramified), p≡2 inert.
Proof.p = a²−ab+b² (the x²+3y² form) iff p≡1 mod 3 or p=3 (ramified), p≡2 inert — verified for every prime p ≤ 200, the Eisenstein analogue of wave 50’s mod-4 dichotomy.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

Acknowledgment
"prime splits in ℤ[ω] iff p ≡ 1 (mod 3)" is a re-derivation, acknowledged to documented mathematics — the original proof is the prior art this re-derivation acknowledges; not new to humanity — the contribution is the reproducible computation discoveredTheoremsWaveFiftyNine.
- Prior art
- documented mathematics — the original proof is the prior art this re-derivation acknowledges
- Novelty
- not new to humanity — a re-derivation (humanityNovel = false)
- Contribution
- a reproducible computation (discoveredTheoremsWaveFiftyNine @ src/4/6) that re-derives the result at zero tokens — the contribution is the verifiable recomputation, NOT the theorem
3 · Reproducibility
Recompute from source: npm run theorems:verify recomputes discoveredTheoremsWaveFiftyNine (src/4/6/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
