[#R1152] Current status and unresolved remainder
claim. UNKNOWN as of 2026-07-31. A 2020 answer on the source page describes the characteristic-zero problem as widely open. Later checked work proves special cases and criteria, with no universal proof or complex counterexample found. Prove that every irreducible curve \(C\subset\mathbb P^3_{\mathbb C}\) is the set-theoretic intersection of two surfaces, with no degree restriction.
1Summary
UNKNOWN as of 2026-07-31. A 2020 answer on the source page describes the characteristic-zero problem as widely open. Later checked work proves special cases and criteria, with no universal proof or complex counterexample found.
A complete resolution must satisfy this condition: Prove that every irreducible curve \(C\subset\mathbb P^3_{\mathbb C}\) is the set-theoretic intersection of two surfaces, with no degree restriction.
Supported evidence. Replay readiness: source only.
