It is composed of two parts. The first part discusses some aspects of timelike T-duality. We explore the possibility of compactification of supergravity theories with various signatures (low energy limit of $M$-theories which are dual under timelike T-dualities) on parallelizable internal seven dimensional (pseudo-)spheres. We show that, beside the standard theory, only one of the dual theories known as $M'$-theory can admit such a solution. The effective four dimensional theory is non-supersymmetric and due to the presence of","authors_text":"Arash Ranjbar","cross_cats":["math-ph","math.DG","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-10-05T17:03:31Z","title":"String Dualities and Gaugings of Supergravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.02793","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:ca1883d8d56ad0e1dcbcd0f59e903766a0cb237e3de5a486ab790ccf92b43ea0","target":"record","created_at":"2026-05-18T00:04:00Z","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":"0197561011f9f0d2227720a6fbbe391d6a5dfa9a5bc35c05786321e314659241","cross_cats_sorted":["math-ph","math.DG","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-10-05T17:03:31Z","title_canon_sha256":"3d7aea8063ce3ef93ef015dd8c06e22c228ca62dbb7288bd28354444cfa9d7ed"},"schema_version":"1.0","source":{"id":"1810.02793","kind":"arxiv","version":1}},"canonical_sha256":"ceaa02bd48de99ab150345d9f5106c6fa5c06d042230d3f4c527d7602dfdbd7e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ceaa02bd48de99ab150345d9f5106c6fa5c06d042230d3f4c527d7602dfdbd7e","first_computed_at":"2026-05-18T00:04:00.644101Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:04:00.644101Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"aeHf5Y5IMu430+r8KbNFwacyatOdADoF1jkZOW6J9C1xAStKojGvtl/S4cpuWa8DyDj/SJfnyX7CtmFNVyw4AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:04:00.644906Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.02793","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ca1883d8d56ad0e1dcbcd0f59e903766a0cb237e3de5a486ab790ccf92b43ea0","sha256:468271fdad704de05a9293e7652ccffc4d17c71552bae5e6823d67f563a75fd5"],"state_sha256":"64e5417d2e3ab01308f97548457e84fdb4eab9628fa97d7bfdd09486a5a2c763"}
