Hence, two total and strict spatial heap operations are proposed upon heap graphs, for conjunction and disjunction -- similar to logical conjuncts. Heap conjunction implies that there exists a free heap vertex to connect to or an explicit destination vertex is provided. Essentially, Burstall's properties do not change. By heap we refer to an arbitrary simple directed graph, which is finite and may contain composite vertices repr","authors_text":"Kirill Krinkin, Ren\\'e Haberland","cross_cats":["cs.FL"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2019-05-30T10:18:58Z","title":"A Non-repetitive Logic for Verification of Dynamic Memory with Explicit Heap Conjunction and Disjunction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1905.12944","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":"sha256:531e9a73fef9d8e389503617d5d2c948387f3135ef9aaea278e46c2401acb9d0","target":"record","created_at":"2026-05-17T23:44:39Z","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":"63e5532b58b6a1296d2b96db320047bf06fbeba0b4c1438f7833e70a0c296b58","cross_cats_sorted":["cs.FL"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LO","submitted_at":"2019-05-30T10:18:58Z","title_canon_sha256":"acb20279472c4c00b98784ba2413be05db57a4d6d0dbe31f909ffa3bd9975863"},"schema_version":"1.0","source":{"id":"1905.12944","kind":"arxiv","version":1}},"canonical_sha256":"db1611dca32573a29371682ab8135f070f4a931f85669fdbf1ff7ccd840a5946","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"db1611dca32573a29371682ab8135f070f4a931f85669fdbf1ff7ccd840a5946","first_computed_at":"2026-05-17T23:44:39.284040Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:44:39.284040Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"08QNzIqNHEkvgmf75DnJI7k09/2jg0dowB+Y4xBDK2zov8ZDRi/dABz0orI5Z0QnXicLBK2YpP/RYoCLe1P0BQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:44:39.284709Z","signed_message":"canonical_sha256_bytes"},"source_id":"1905.12944","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:531e9a73fef9d8e389503617d5d2c948387f3135ef9aaea278e46c2401acb9d0","sha256:8a8e1393ae2587302534736b21bd8d7a9984abafa66ba828165e0d6596f10b13"],"state_sha256":"bd17d04305f8aabeee7da5d935a5af8376f7286f70b2655bddc0f826e71d084c"}
