A Proof of the Sunflower Conjecture
We prove the Sunflower Conjecture of Erdős and Rado (1960): there exists a constant C(k) depending only on k such that any family of more than C(k)^r sets of size r contains a k-sunflower. We establish C(k) = (k-1)², proving that any r-uniform k-sunflower-free family F satisfies |F| ≤ (k-1)^{2r}. For k = 3, this gives |F| ≤ 4^r.

On the Sunflower Conjecture: Computational Bounds and an Unsuccessful Proof Attempt
CORRECTION NOTICE (v2, January 15, 2026): Version 1 claimed a proof of the Sunflower Conjecture. This claim is RETRACTED. Mathematician Thomas Bloom identified a fundamental error: Lemma 4.2 incorrectly bounds the piercing number independently of r, which is known to be impossible. The main theorem does not follow.

It is well known that Erdős Matching Conjecture concerns the maximum number of hyperedges in an $r$-uniform hypergraph with bounded matching number. As a generalization, it is natural to ask for the maximum number of copies of subhypergraphs. Given integers $r\geq2$ and $k\ge 1$, let $S_{r-1,k}^r$ denote the $r$-uniform hypergraph with hyperedges ...

Exact Values and a Conjectured Formula for Maximum Sunflower-Free Families
Version 3 — First Public Release (January 14, 2026) Major revision with new theoretical framework and extended computations. What's New in V3: • NEW: Conjectured formula m(n,3) = (8/3)·(3/2)^(n-1) — exact for n=2,3,4, matches to 98.8% for n=5,6,7,8 • NEW: Optimized parallel solver with intersection indexing (P1-P4 improvements) • NEW:
