On the violation of Bell’s inequality in quantum theory

This note records only the bibliographic record for Landau’s article. Crossref identifies Lawrence J. Landau as the author and records the article in Physics Letters A 120(2), 54-56 (1987), DOI 10.1016/0375-9601(87)90075-2.

The article’s full text was not readable during this review. No claim is made that it states, proves, or contains the exact local-commutativity corollary formalized at D5/S3/QuantumBounds/LandauCommutingCollapse. That corollary remains repository-derived; the article is cited only as contextual historical credit.

Search log

• 2026-08-15: Crossref DOI metadata was queried directly. It identifies Lawrence J. Landau, the exact title, Physics Letters A 120(2), 54-56 (1987), DOI 10.1016/0375-9601(87)90075-2.
• 2026-08-15: OpenAlex was queried by DOI. It reports is_oa=false, closed OA status, no OA URL, and no repository full text.
• 2026-08-15: The DOI resolved to Elsevier. A direct ScienceDirect article request returned HTTP 403, and the Elsevier text-mining request returned HTTP 406 without article content, so no full text was read.
• 2026-08-15: A Semantic Scholar API request returned HTTP 429. Its reported access status was therefore not independently verified and is not relied on here.
