The main difficulty lies in a constructive description of the invariant ring of $\\mathrm{GL}(2, K)$ on $m$ copies of $\\mathrm{SL}(2, K)$ by simultaneous conjugation. By giving this description, we generalize and simplify some of the known results in invariant theory. An implementation of the algorithm is available in the computer algebra system Magma.","authors_text":"Sebastian Jambor","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.GR","submitted_at":"2014-02-27T04:41:44Z","title":"An L2-quotient algorithm for finitely presented groups on arbitrarily many generators"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.6788","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":"sha256:1fce8a359b95b7b89bdafb24ebd740c886a6fd199737700ae23619d72faea500","target":"record","created_at":"2026-05-18T02:57:37Z","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":"ed0ba6f4f974e6a8a59f89e4a31b207a9551755029a254c744ae08c433723ea0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.GR","submitted_at":"2014-02-27T04:41:44Z","title_canon_sha256":"bf8b4acca9bd80ec8a29c01ca932903199c1b26a63e9d0a0a34c03b17911ed06"},"schema_version":"1.0","source":{"id":"1402.6788","kind":"arxiv","version":1}},"canonical_sha256":"a11d888b44d44b982a198b7d3c0e361b2a1fd12424bd4d4e859411fd9da4b20b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a11d888b44d44b982a198b7d3c0e361b2a1fd12424bd4d4e859411fd9da4b20b","first_computed_at":"2026-05-18T02:57:37.032491Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:57:37.032491Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"K4VFmMNe/coIOsCP2jA26r1zvER+V4Ksdp50QoHrqcAb31TecQ1Vft6rHA7dd8C6F5rQzvRk9R0Ivycxgc6MCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:57:37.033253Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.6788","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1fce8a359b95b7b89bdafb24ebd740c886a6fd199737700ae23619d72faea500","sha256:f78b6b23bce93d5f8e8ada2a5121650c115dda19e8b7871b40fda21c5b412bcc"],"state_sha256":"bb1f12739a482d2ea8ab799cbbcd05101e39cc40f3d0c10d54331748368b89d0"}
