We illustrate cosmological dynamics in such models for the case of the hyperbolic triply-punctured sphere.","authors_text":"Calin Iuliu Lazaroiu, Elena Mirela Babalic","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-01-10T12:57:56Z","title":"Two-field cosmological models and the uniformization theorem"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.03356","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":"sha256:4acb20deb40048b2e947c1bb1ff8d602778ba539aba39531fc9504e860583c84","target":"record","created_at":"2026-05-17T23:49:28Z","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":"3d09f70f0ccba703eda83b87e3520493c839f0c457a6c05f10bc787b34d13b45","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-01-10T12:57:56Z","title_canon_sha256":"d367edd3aff82b07bcb17da11e97a5065132018c578d3776823062f8959633a4"},"schema_version":"1.0","source":{"id":"1801.03356","kind":"arxiv","version":1}},"canonical_sha256":"9059f0df0d5486a558f51f1edde18f4515829fcc45c17ef7d80df5be749f2c3f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9059f0df0d5486a558f51f1edde18f4515829fcc45c17ef7d80df5be749f2c3f","first_computed_at":"2026-05-17T23:49:28.742370Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:28.742370Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0KtTTjNlGpfeEaSybf61/TOCQlEmLmZowhwZKO9ggalUmuHJG8J0BanhzDklaTdGJmBszmQ9VO5PvCwJ3M57AA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:28.742847Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.03356","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4acb20deb40048b2e947c1bb1ff8d602778ba539aba39531fc9504e860583c84","sha256:5fddf8683854f9802796e036e91d6cb923c2d32748be045a1195993dd917efb9"],"state_sha256":"890ffe4314685ee3d27c5aa3dd596ba3e27c2b0d12d4d6af78c989156193dc77"}
