The local action depends of the square root of the quadratic mean extrinsic curvature of the worldsheet swept out by the string, and is reparametrization invariant. A general expression for the worldsheet perturbations, guided by Jacobi equations without any early gauge fixing, is obtained. This is manifested through a set of highly coupled nonlinear differential partial equations where the perturbations are describ","authors_text":"Efrain Rojas","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-11-03T04:03:56Z","title":"Covariant perturbations in the gonihedric string model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.01019","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":"sha256:5cf8f966475c38bf600bc6d5d0425a43b574afedaaf651d78900608b17215b83","target":"record","created_at":"2026-05-18T00:29:45Z","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":"60c3f28756ed64bdf8e8862a2c4c217a8c400b97353bbcbcbed26f330fc10fe6","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-11-03T04:03:56Z","title_canon_sha256":"dd256be22f9c2d6747c02887fce60d5b35d3758dcc19043b3c14142c1eab7af8"},"schema_version":"1.0","source":{"id":"1711.01019","kind":"arxiv","version":2}},"canonical_sha256":"018be8dc8d69911225f7e38c8abf2de50fe05dc40cb5bc09dc74507392a0e718","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"018be8dc8d69911225f7e38c8abf2de50fe05dc40cb5bc09dc74507392a0e718","first_computed_at":"2026-05-18T00:29:45.288987Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:29:45.288987Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PQytAfYLKHsfL7YvOe1VPAirxoyyuX6r0CEmIJidbIZevoROMOAckZXDpPxiJ1XpDi0yG+7Ub+w0qLhYoHxgBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:29:45.289647Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.01019","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5cf8f966475c38bf600bc6d5d0425a43b574afedaaf651d78900608b17215b83","sha256:2ff026da88e101fa7b22b075caf3bd18b9088962d7745e0ca2fb252c13d5c4d6"],"state_sha256":"5ac7d83fbdda39780a27a9508f72bb2ed73fd478485ec75ab4846c369461c01f"}
