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.

    The three-dimensional case of this result was proven by Wilhelm Blaschke (1917); the full result was proven much later by Luis Santaló (1949) using a technique known as Steiner symmetrization by which any centrally symmetric convex body can be replaced with a more sphere-like body without decreasing its Mahler volume.
