Instead of explicitly computing a partial series of high-order diagrams, as in perturbative resummation schemes, we embed the standard perturbation theory within a realistic nonlinear Lagrangian-space ansatz. We also point out that an \"adhesion-like\" regularization of the shell-crossing regime is more realistic than a \"Zel'dovich-like\" behavior, where particles freely escape to infinity. This provides a \"cosmic web\" power spectrum with good small-scale properties","authors_text":"Atsushi Taruya, Patrick Valageas, Takahiro Nishimichi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-02-19T07:41:05Z","title":"Matter power spectrum from a Lagrangian-space regularization of perturbation theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.4533","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":"sha256:264d344703794db7feaa20a1107531e042a7e7025852ca23f96bbec91e04b116","target":"record","created_at":"2026-05-18T03:25:34Z","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":"b809bb39af9dce5a9562309a6dd549396e4b42240e203be912c2d4666f2db58d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-02-19T07:41:05Z","title_canon_sha256":"0cc60877361d5544079656a738e64bea903e97ea5a5830baf6a837c8a9c4a64a"},"schema_version":"1.0","source":{"id":"1302.4533","kind":"arxiv","version":2}},"canonical_sha256":"53c1fd4b7bf9497f0cd2c7f34f7fde0b30c7f7c42fae3c45a7a8fdf5be283991","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"53c1fd4b7bf9497f0cd2c7f34f7fde0b30c7f7c42fae3c45a7a8fdf5be283991","first_computed_at":"2026-05-18T03:25:34.592385Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:25:34.592385Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Jh5ZBV0e2jMwXQQiEZ+NN0TtZf+jWuRJRjr+1eD3bsUYJiC25WoqRzjJN8qZh+AgAM7ASZUT0xWJfEc/Av7dAg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:25:34.593074Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.4533","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:264d344703794db7feaa20a1107531e042a7e7025852ca23f96bbec91e04b116","sha256:6f636e7a87e6825f1e3dbe24fd8f6f01d10963e900cf9fadf98a76251b8f600a"],"state_sha256":"66ce1ec380950655903d6156d2e8f429f7710ab36e02d1b5c877795a2d187275"}
