Assuming that the universe is filled by a fluid with equation of state (EoS) $P=-\\rho-f(\\rho)$, for different teleparallel theories and different EoS we study its dynamics. Two particular cases are studied in detail: in the first one we consider a function $f$ with two zeros (two de Sitter solutions) that mimics a huge cosmological constant at early times and a pressureless fluid at late times. In the second one, in the context of loop quantum cosmology with a small cosmological constant, we consider a pressu","authors_text":"Jaume Amoros, Jaume de Haro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-11-22T17:12:46Z","title":"Non-singular models of universes in teleparallel theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1211.5336","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":"sha256:9b2c88e5eb7dba2b076977102d9f73f6c31e3e18703c5687ebb4c1e1691c9185","target":"record","created_at":"2026-05-18T01:53:01Z","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":"3b002259f01491fc71ab11fb36a4fd72db961be7d001f1333fe34f67e2170df4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-11-22T17:12:46Z","title_canon_sha256":"ec41ba695045550905c3c42dc9ac3f74463d2b9b6b41840bc3548d0614f78ee8"},"schema_version":"1.0","source":{"id":"1211.5336","kind":"arxiv","version":2}},"canonical_sha256":"a3b3113ef01abdbca830b23b104415422a7e4b4e32f286b2bff93c781705f76f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a3b3113ef01abdbca830b23b104415422a7e4b4e32f286b2bff93c781705f76f","first_computed_at":"2026-05-18T01:53:01.452631Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:53:01.452631Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ui8HsMmQpjJYLZdrDNPnara9b0e7RmDMwNqjhpxfT97PM79GZXUjPqf/n2wToO8AttOHhK9JgNPVSk9z0PkqCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:53:01.453334Z","signed_message":"canonical_sha256_bytes"},"source_id":"1211.5336","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9b2c88e5eb7dba2b076977102d9f73f6c31e3e18703c5687ebb4c1e1691c9185","sha256:be82b3721d0fd85ee7afd7251ce1f0ec41315f6473396934f805f25d9eb331fa"],"state_sha256":"f30647deeb54f9a70ea2e91c079e2efb5a321ed57bc805fc91978d42cce3a9d9"}
