Rev. D 78 (2008), 085003, 5 pages, arXiv:0809.2874] the two-Hilbert-space (2HS, a.k.a. cryptohermitian) formulation of Quantum Mechanics has been revisited. In the present continuation of this study (with the spaces in question denoted as ${\\cal H}^{\\rm (auxiliary)}$ and ${\\cal H}^{\\rm (standard)}$) we spot a weak point of the 2HS formalism which lies in the double role played by ${\\cal H}^{\\rm (auxiliary)}$. As long as this confluence of roles may (and did!) lead to confusion in the literature, we propose an amended, three-Hilbert-space (3HS) reformulation of the sa","authors_text":"Miloslav Znojil","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"quant-ph","submitted_at":"2009-01-06T19:42:37Z","title":"Three-Hilbert-Space Formulation of Quantum Mechanics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.0700","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9d4811305b7098cf6e0f5dad5b8502a2990f49623a9c02e7984d851cc42a0312","target":"record","created_at":"2026-07-04T15:35:31Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"7a44a7524e176f140f4c579d102117d28a07f84a9328a4f0c813fc84b97c757f","cross_cats_sorted":["math-ph","math.MP"],"license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"quant-ph","submitted_at":"2009-01-06T19:42:37Z","title_canon_sha256":"1a1e27209f78672246841fd7e34ab6ff29c3f8119c35df99a04df61a5168fb9c"},"schema_version":"1.0","source":{"id":"0901.0700","kind":"arxiv","version":1}},"canonical_sha256":"05adc96116c7dfdbb9d644eba1deeed5f4b7cf0b56a47815f497a4b7a8060eda","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"05adc96116c7dfdbb9d644eba1deeed5f4b7cf0b56a47815f497a4b7a8060eda","first_computed_at":"2026-07-04T15:35:31.692309Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:35:31.692309Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2mrlGrULAYEeKUD5QFTwGZih+YXeVCBYfbHPM2knhVdSS9h40nJMaV24EeJtKnJN8CkSZsSyhJhOf+oMIoJ8Bw==","signature_status":"signed_v1","signed_at":"2026-07-04T15:35:31.692698Z","signed_message":"canonical_sha256_bytes"},"source_id":"0901.0700","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9d4811305b7098cf6e0f5dad5b8502a2990f49623a9c02e7984d851cc42a0312","sha256:342003cee8498940f6c234da38b77af6622883987b50b6f390d45fa29a547bab"],"state_sha256":"cfce3962571dffea41e05fd9a00f459e61ff5263a2c36024268ed7f4c6131b35"}
