OpenAI reports a complete higher-dimensional symplectic ball-packing criterion

For n≥3, finitely many closed standard symplectic 2n-balls of positive capacities Rᵢ embed disjointly into the interior of a ball of capacity R exactly when the sum of Rᵢⁿ is below Rⁿ and every pair satisfies Rᵢ+Rⱼ<R.

Read the background

For n≥3, finitely many closed standard symplectic 2n-balls of positive capacities Rᵢ embed disjointly into the interior of a ball of capacity R exactly when the sum of Rᵢⁿ is below Rⁿ and every pair satisfies Rᵢ+Rⱼ<R.

Why it matters

If correct, resolves Siegel and Yao’s high-dimensional ball-packing conjecture for arbitrary finite collections of capacities.

What counts as progress

Are volume and two-ball constraints sufficient for symplectic ball packing in dimensions at least six?
