When the minimum cut value between each source-destination pair is constrained to be 1, it is obvious that the triangular rate region {(R_1,R_2):R_1,R_2> 0, R_1+R_2< 1} can be achieved, and that one cannot achieve beyond the square rate region {(R_1,R_2):R_1,R_2> 0, R_1< 1,R_2< 1}. Analogous to the work by Wang and Shroff for wired networks, we provide the necessary and sufficient conditions for the capacity region to be the triangular region and the necessary and sufficient c"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1105.6326","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
