The nonlinear interconnected system is characterized by saturated nonlinearities that describe how agents transmit their opinion state to their neighbors in the hypernetwork, and by a bifurcation parameter representing the community's social effort. We show that the presence of higher-order interactions leads to the unfolding of a pitchfork bifurcation, introducing an interval for the social effo","authors_text":"Angela Fontan, Silun Zhang","cross_cats":["cs.MA","cs.SY","eess.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2025-09-05T15:30:36Z","title":"Collective decision-making dynamics in hypernetworks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.05182","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":"sha256:352fab2bd3a0e694202fd32756181c2fd1939f8a8511b74a58c9fabbba883bfb","target":"record","created_at":"2026-07-05T12:05:37Z","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":"173aae626dc2fe3d5b46d01deeded56203091fd421f0319c41a3e4391f8f1137","cross_cats_sorted":["cs.MA","cs.SY","eess.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2025-09-05T15:30:36Z","title_canon_sha256":"d2268f641f90ac3de681b6e6b570152cb7860fb1838106fc053443f22b06eafc"},"schema_version":"1.0","source":{"id":"2509.05182","kind":"arxiv","version":1}},"canonical_sha256":"bcb35c9092db879a2ab6d9a978f382d65858a5d10f42dfc5a731db3ecd280405","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bcb35c9092db879a2ab6d9a978f382d65858a5d10f42dfc5a731db3ecd280405","first_computed_at":"2026-07-05T12:05:37.416548Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:05:37.416548Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZvL5r8bk28YpQaHGQEH7vbXCmxAVIu/+Dv5cPe0cKRPT0XqW01mH5EjdfSssgbig2CtFcBRC2iZuKkp0rRzTAA==","signature_status":"signed_v1","signed_at":"2026-07-05T12:05:37.417021Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.05182","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:352fab2bd3a0e694202fd32756181c2fd1939f8a8511b74a58c9fabbba883bfb","sha256:245f65b69b42083d89dacec858735a1e01ed0b2b7b487fbe8932f05fd1f52b44"],"state_sha256":"ab7ffedf2a9f0192459be9a820c425a61162c9effc46bfc57103ad9a7d03ad56"}
