Ollivier. This function can be used to recover the Ricci tensor on smooth Riemannian manifolds by the formula $$ \\mathrm{Ric}(\\gamma^{\\prime}\\left( 0\\right) ,\\gamma^{\\prime}\\left( 0\\right) )=\\frac{1}{2}\\frac{d^{2}}{ds^{2}}\\mathrm{Ric}_{\\Delta_g}(x,\\gamma\\left( s\\right) )$$\n  for any curve $\\gamma(s).$"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1505.04166","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"}
