Using Fourier analytic tools with a third moment method, we obtain sum-product type estimates for subsets of $\\mathbb{F}_q$. In particular, we prove that if $A\\subset \\mathbb{F}_q$, then $$|AA+A|,|A(A+A)|\\gg\\min\\left\\{q, \\frac{|A|^2}{q^{\\frac{1}{2}}} \\right\\},$$ so that if $A\\ge q^{\\frac{3}{4}}$, then $|AA+A|,|A(A+A)|\\gg q$."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.07876","kind":"arxiv","version":2},"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"}
