In this work we carry out a phase-space analysis of ultra-slow roll in an arbitrary potential, $V(\\phi)$. We show that while standard slow roll is always a dynamical attractor whenever it is a self-consistent approximation, ultra-slow roll is stable for an inflaton field rolling down a convex potential with $M_{\\scriptscriptstyle{\\mathrm{Pl}}} V''>|V'|$ (or for a field rolling up a concave potential with $M_{\\scriptscriptstyle{\\","authors_text":"Chris Pattison, David Wands, Hooshyar Assadullahi, Vincent Vennin","cross_cats":["gr-qc","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2018-06-25T16:27:47Z","title":"The attractive behaviour of ultra-slow-roll inflation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.09553","kind":"arxiv","version":2},"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":"sha256:6d83101c316deb3bea50df1b1d5004068d769717d7b059fb99d81e0cf2720e39","target":"record","created_at":"2026-05-18T00:05:30Z","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":"20a1f72362e4b1832a1e2f314796882ef74e96851064dfed663434425641b50d","cross_cats_sorted":["gr-qc","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2018-06-25T16:27:47Z","title_canon_sha256":"7b596d1e9cd8843f7074b417715741b7ca2c79b8e64ff62a84bef48e63671a25"},"schema_version":"1.0","source":{"id":"1806.09553","kind":"arxiv","version":2}},"canonical_sha256":"06d9bcb25a7d0af01b43b1b9971a23f855be7fd50c490e122385de3ef492b233","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"06d9bcb25a7d0af01b43b1b9971a23f855be7fd50c490e122385de3ef492b233","first_computed_at":"2026-05-18T00:05:30.655235Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:05:30.655235Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qJcLpckc53axS8fUBtQUEmn0Eh6fCZ2tmD1GQM1pGb8Ovf6HavGRxJVZ8DJFAoDHh97B95P3IWbumOP542a5DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:05:30.655769Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.09553","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6d83101c316deb3bea50df1b1d5004068d769717d7b059fb99d81e0cf2720e39","sha256:fb6c4bf957ba2a4f434d0f9deed91ed83f0f932431650420a3d2d67c1ab7c230"],"state_sha256":"762d397e72c4e7bb9eaa21a5ed56a206e9e1353fb94b9378251e5fb6ff2d7d79"}
