Following Witten's spinor argument, it is argued that a single condition should be imposed upon a gauge connection in the super-covariant derivative. Under this condition, we present a simple formula for the divergence of the Nester tensor in Einstein's gravity with general source. Applying this prescription to the Einstein-scalar system, we find that for a certain class of the gauge connection, a special kind of non-canonical scalar-field theory admits the positivity property in addition to","authors_text":"Masato Nozawa, Tetsuya Shiromizu","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2013-10-07T03:01:47Z","title":"Modeling scalar fields consistent with positive mass"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.1663","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":"sha256:3691d917016e9677885a2b445ecfdad5b17d97b4dcdcd01102c9c56eebec2cc4","target":"record","created_at":"2026-05-18T02:56:51Z","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":"97b66bfc6c1c1d195c6b91398ec1d4a0a5a0947bbb2807f67dda4d32c33cd908","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2013-10-07T03:01:47Z","title_canon_sha256":"6474d6658a42f013cc3e8f4c031605e7828059a2c8a0a851a2e64218cbfd7deb"},"schema_version":"1.0","source":{"id":"1310.1663","kind":"arxiv","version":2}},"canonical_sha256":"ee6dda8eb2835ee09d1368277db19d7d4ed9305c19cfc7c01d05b0036942f0f8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ee6dda8eb2835ee09d1368277db19d7d4ed9305c19cfc7c01d05b0036942f0f8","first_computed_at":"2026-05-18T02:56:51.798728Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:56:51.798728Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/gfNcCiy6QRmNqpZ0G2tcPQyBOb+i3LV7UEVcRSeglwwDgaJ+YlOObpSQwBVV+aRikkevRHiaSdQ7KedffA4Aw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:56:51.799285Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.1663","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3691d917016e9677885a2b445ecfdad5b17d97b4dcdcd01102c9c56eebec2cc4","sha256:4fb6af61a1322e26ebd282a74b53cb3ec97f77c69442af4d03d1a9db82dbab92"],"state_sha256":"85b6edb4cdc95b007d4a38bae060c602a9700f09e060c4d1d21132db46d54ee4"}
