Combining the linearization method of Andersson \\cite{An16} and the epiperimetric inequality from \\cite{FS16}, \\cite{GPSVG15}, we prove the optimal $C^{1,\\min\\{\\alpha,1/2\\}}$ regularity of solutions in the presence of $C^{0,\\alpha}$ coefficients $a^{ij}$ and $C^{1,\\alpha}$ obstacles $\\phi$. Moreover we investigate the regularity of the regular free boundary and show that it has the structure of a $C^{1,\\gamma}$ manifold for s"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.07961","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"}
