Two realistic non-minimal torsion-matter coupling $f(T)$ models have been established and studied in our previous papers [Phys. Rev. D92, 104038(2015) and Eur. Phys. J. C77, 504(2017)] aiming to explain this \"dark energy\" problem. In this paper, we study the generalized power-law torsion-matter coupling $f(T)$ model. Dynamical system analysis shows that the three expansion phases of the Universe, i.e. the radiation dominated era, the matter dominated era and the da","authors_text":"Qiang Wen, Rui-Hui Lin, Xiang-Hua Zhai, Xin-zhou Li","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-03-12T07:11:08Z","title":"Diagnostics for generalized power-law torsion-matter coupling $f(T)$ model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.04134","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:edb1a0d0607da66bcf14b07524e1c2b1f1497b9d4ccc3df9f0bd1cea36443182","target":"record","created_at":"2026-05-18T00:21:32Z","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":"87b097d48395d32c5d2137485e2f11f8106ce8e58abe630dcb9514cf9416eb2b","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2018-03-12T07:11:08Z","title_canon_sha256":"c2cfe00ad57b39a55cb56cc7e206bd0d47c648fd3a76c88a457478b72ae3345f"},"schema_version":"1.0","source":{"id":"1803.04134","kind":"arxiv","version":1}},"canonical_sha256":"2b2137e54f5599954099e1a8f0032b242d45d6591eaea5024547ca581e517e31","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b2137e54f5599954099e1a8f0032b242d45d6591eaea5024547ca581e517e31","first_computed_at":"2026-05-18T00:21:32.547733Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:21:32.547733Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MjBv7s0Y/qcNT9vPjPdvS8EhDmmGIhp3ACG32cUJJ+lFv0TyZe97ayIrxytGVne4Hg0uO4DjargvafYiI/IqAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:21:32.548428Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.04134","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:edb1a0d0607da66bcf14b07524e1c2b1f1497b9d4ccc3df9f0bd1cea36443182","sha256:bb1971c8e2dd4e8c63bb32aacfa5cdcd28a4a414d68dff75873f98d059bac7f9"],"state_sha256":"cadf64534bfe1695e548971e8e3ec1ac27b92e2412ab156720327ada3987aa56"}
