This generalizes recent work by Schn\\\"urer and Schulze which treats the case of three half-lines. There are multiple solutions, and these are parametrized by combinatorial objects, namely Steiner trees with respect to a complete negatively curved metric on the unit ball which span $k$ specified points on the boundary at infinity. We also provide a sharp formulation of the regularity of these solutions at $t=0$.","authors_text":"Mariel Saez, Rafe Mazzeo","cross_cats":["math.AP"],"headline":"","license":"","primary_cat":"math.DG","submitted_at":"2007-04-24T04:12:38Z","title":"Self similar expanding solutions of the planar network flow"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0704.3113","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":"sha256:0a09f1f822a4c4ccd87ce740cffcc79f3c31c64361cc270063b0ff0a14f832b0","target":"record","created_at":"2026-07-04T15:01:02Z","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":"901c36bc30c5834c8613ce95bd7c6c95ef0aadece7bee8b51f61b4f94664d513","cross_cats_sorted":["math.AP"],"license":"","primary_cat":"math.DG","submitted_at":"2007-04-24T04:12:38Z","title_canon_sha256":"5813db45cc9aa8af3c9032fea7812d7c22309372d0364df47408a2cc7b7581d4"},"schema_version":"1.0","source":{"id":"0704.3113","kind":"arxiv","version":1}},"canonical_sha256":"9ad0718dabcf79a6ca306287deba3b556340ea07ed1e743764a25d221422c79c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9ad0718dabcf79a6ca306287deba3b556340ea07ed1e743764a25d221422c79c","first_computed_at":"2026-07-04T15:01:02.475925Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:01:02.475925Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Suj4KC5MuvxDgWaCWMKBWka/H5fqGpWqS8htV2yAnZE0hSZw3l9IeG72x9UQEdEuPpyCJkOA/hxod7Oqzv7qDg==","signature_status":"signed_v1","signed_at":"2026-07-04T15:01:02.476295Z","signed_message":"canonical_sha256_bytes"},"source_id":"0704.3113","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0a09f1f822a4c4ccd87ce740cffcc79f3c31c64361cc270063b0ff0a14f832b0","sha256:9855667174f57d75e76da0a04ed926e146d64b5bfee2c3efe13095e10ec9eec9"],"state_sha256":"ef428682a07b796835b3f6cdee3a314d27980314265ecc8b2e85165b4c774a57"}
