Recent methods for self-force calculations avoid delta functions altogether, using instead a finite and extended \"effective source\" for a point particle. We provide a review of the general principles underlying this strategy, using the specific example of a scalar point charge moving in a black hole spacetime. We also report on two new developments: (i) the construction and evaluation of an effective source for a scalar charge moving along a generic orbit of an arbitrary space","authors_text":"Barry Wardell, Ian Vega, Peter Diener","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2011-01-14T22:43:08Z","title":"Effective source approach to self-force calculations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.2925","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:b5b8dc0ddb086b0f343dc863d5999e2f12b1ed45325045795a1e1f2ce53742c4","target":"record","created_at":"2026-05-18T02:22:57Z","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":"b247fe5be4d468a79818c747cc44fecdcaa33997a850890268078c8f0f69b33b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2011-01-14T22:43:08Z","title_canon_sha256":"c2defd3ef0a5e1309abf7bca0ef624620c874ec051d2292bd992f6273fde87ac"},"schema_version":"1.0","source":{"id":"1101.2925","kind":"arxiv","version":1}},"canonical_sha256":"2e0b4e6ff7bbfb074be7cba71c2b5cbbde659719b9ecb0ba6e025cc8e204eda6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2e0b4e6ff7bbfb074be7cba71c2b5cbbde659719b9ecb0ba6e025cc8e204eda6","first_computed_at":"2026-05-18T02:22:57.254701Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:22:57.254701Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NvUTy7rHnNyWzY/KDtIOVLkPFlNQJ8dtwu3K3b3iXYH5TDNAD2cmKr3Y10TYIET64crSsuOmzSGIUlzMOPiWAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:22:57.255352Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.2925","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b5b8dc0ddb086b0f343dc863d5999e2f12b1ed45325045795a1e1f2ce53742c4","sha256:e3db5743a567995db43fb6e7aef8b2b7017f582811aca46d37a38b0d02b7a0c7"],"state_sha256":"55e68d980bc31a89632b9a363036ff6d6cdf4fdc22f9a343945e4a784599dfe1"}
