An example is considered and their predictions are contrasted between Planck 2018 data. We calculate the spectrum indices and the slow-rolling parameters of the effective potential. The results are in very good agreement with observations.","authors_text":"Juan Ignacio Musmarra, Mariano Anabitarte, Mauricio Bellini (IFIMAR - CONICET & UNMdP)","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-05-07T15:17:13Z","title":"Inflationary expansion of the universe with variable timescale"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.02565","kind":"arxiv","version":5},"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:b08373ca6fccc3209c91490b5bcd4b9b21f25d3e09bbc735bc19214b06447a2f","target":"record","created_at":"2026-05-17T23:55:20Z","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":"1d178ea65a89a75c2b221bd56f64580c59c9d4ea7d1ada986aa6341d5c82cad6","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-05-07T15:17:13Z","title_canon_sha256":"eabf01111cb271fa3fd666d631a74b8ed9a08f2cf950a1fb8834604f29c7a091"},"schema_version":"1.0","source":{"id":"1805.02565","kind":"arxiv","version":5}},"canonical_sha256":"3bf0326aa676b61589f5881179b1384249493ee886ec720475e7f5184b9adfc0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3bf0326aa676b61589f5881179b1384249493ee886ec720475e7f5184b9adfc0","first_computed_at":"2026-05-17T23:55:20.831455Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:55:20.831455Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AVfo0xqUSrUFS4LmmXd7osJb8W1WyphR4XNSaIwBtp87nbaVQ83Y3e0mLh3Lcvczo08GeAMlj4yVn1gLQv+8BA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:55:20.831914Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.02565","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b08373ca6fccc3209c91490b5bcd4b9b21f25d3e09bbc735bc19214b06447a2f","sha256:00f82baf49b351eed20efd1ecf2e9f2394e8d2aec3c0da1dbb1cf6d0c0330bf3"],"state_sha256":"3cbb76b08eb22535559645f5a01260e2910f8258df7116d7036806fdb43307a0"}
