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