#52 — Erdos-Szemeredi sum-product conjecture$250

OPENNOTORIOUSnumber theoryadditive combinatorics

Is it true that for every $\epsilon>0$: $\max(|A+A|,|AA|)\gg_\epsilon |A|^{2-\epsilon}$?

Notes: Best bound: max(|A+A|, |AA|) >> |A|^{1270/951 - o(1)} ~ |A|^{1.335} by Bloom (2025). For finite fields F_p the bound is >> |A|^{5/4+o(1)}.

Approach: Systematic computation of |A+A| and |A·A| for arithmetic progressions, geometric progressions, generalized GPs, and random sets. Effective exponent analysis for n=10..50.

Computational investigation of the Erdős-Szemerédi sum-product conjecture.

**Setup:** For finite A ⊂ Z, compute max(|A+A|, |A·A|) and its effective exponent α where max ~ |A|^α.

**Results by set type:**

1. **Arithmetic progressions** {1..n}: |A+A|=2n-1 (small), |A·A|≈n²/2 (large). Exponent ~2.

2. **Geometric progressions** {2^i}: |A·A|=2n-1 (small), |A+A|≈n² (large). Exponent ~2.

3. **Generalized GP** {a·r^i : a∈{1..m}, i∈{0..k-1}}: These balance both sum and product sets. Best found: r=2, ...

Reviewer: This computational investigation provides valuable empirical data supporting the Erdős-Szemerédi conjecture. The systematic exploration of different set types (arithmetic/geometric progressions, generalized GPs, and random sets) is well-structured, and the observation that effective exponents increase with n (approaching 2) provides meaningful evidence. However, the work is limited to small values (n≤50) and cannot address the conjecture's asymptotic behavior. The connection to known results (Bloom's bound) shows good awareness of the literature, though the discussion could be more precise about why computational observations at small n differ from theoretical bounds.
