Let (M^n,g(t)) with t\\in [-T,0] be a Ricci flow and H_{x} the conjugate heat kernel centered at a point (x,0) in the final time slice. Substituting H_{x} into Perelman's W-functional produces a monotone function W_{x}(s) of s \\in [-T,0], the pointed entropy, with W_{x}(s) <= 0, and W_{x}(s) = 0 iff (M,g(t)) is isometric to the trivial flow on R^n. Our main theorem asserts the following: There exists an \\epsilon>0, depending only on T and on lower scalar curvature and \\mu-entropy bounds for (M,g(-T)), such that W_{x_0}(","authors_text":"Aaron Naber, Hans-Joachim Hein","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.DG","submitted_at":"2012-05-02T11:07:56Z","title":"New logarithmic Sobolev inequalities and an \\epsilon-regularity theorem for the Ricci flow"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.0380","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":"sha256:524b2ef9bdd3ff7f2812e133163424fcdd0dfd0182eb5426d4b813d9fe224d05","target":"record","created_at":"2026-05-18T03:56:34Z","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":"aeee7a9f13672c082cc16ff698321a352ad33f4de5f38369bfb23e08d2ad20af","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.DG","submitted_at":"2012-05-02T11:07:56Z","title_canon_sha256":"d0600e35f4ef67997a09b2214e4ea26710aaa602442295da85b62bb2734c0800"},"schema_version":"1.0","source":{"id":"1205.0380","kind":"arxiv","version":1}},"canonical_sha256":"39f7cb86050a332f8d38e2c82e32f807896a8da9ed773b2c8273233cc54a5c89","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"39f7cb86050a332f8d38e2c82e32f807896a8da9ed773b2c8273233cc54a5c89","first_computed_at":"2026-05-18T03:56:34.687126Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:56:34.687126Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6dgwhL3YSxJ5Wezmnc3r9tSXd8CxX4aVK2F0qwq+0rFlFPuQ4qsPD7h5lgmByr795iG9M+sd4+LBdPnNngqaBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:56:34.687656Z","signed_message":"canonical_sha256_bytes"},"source_id":"1205.0380","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:524b2ef9bdd3ff7f2812e133163424fcdd0dfd0182eb5426d4b813d9fe224d05","sha256:616a29daf39cd37953d0720e3b45154e55e88f1f8d15c65446d0a3f3b4ed43d7"],"state_sha256":"1c477d171278c0585e72da2922165b81047d9ac0dbe14c32e4b044d871087acc"}
