Blaschke-Santalo Inequality

Geometry

The Blaschke-Santalo Inequality is a result of convex geometry concerning the Mahler volume, a dimensionless quantity associated with a centrally symmetric convex body that remains unchanged under linear transformations. The inequality establishes that, among all centrally symmetric convex bodies, the ball and the solid ellipsoids attain the largest possible Mahler volume, making them the extremal shapes for this quantity.

Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
