Blaschke-Santaló与仿射等周不等式的稳定性

Stability of the Blaschke-Santaló and the affine isoperimetric inequality

Károly J. Böröczky

摘要:

证明了维数n>2的凸体的Blaschke-Santaló不等式和仿射等周不等式的稳定性.第一步是还原到当凸体是o对称的并且具有轴旋转对称性时的情况。这一步适用于与Steiner对称化兼容的相关不等式。其次,对于这些凸体,建立了一个稳定的版本的特征的事实,每个超平面部分是中心对称的椭球。

英文摘要:

A stability version of the Blaschke-Santaló inequality and the affine isoperimetric inequality for convex bodies of dimension n>2 is proved. The first step is the reduction to the case when the convex body is o-symmetric and has axial rotational symmetry. This step works for related inequalities compatible with Steiner symmetrization. Secondly, for these convex bodies, a stability version of the characterization of ellipsoids by the fact that each hyperplane section is centrally symmetric is established.
