相交体的同构性质

Isomorphic properties of Intersection bodies

A. Koldobsky, G. Paouris, M. Zymonopoulou

摘要:

研究了两种广义交体的同构性质:k-交体类和广义k-交体类。我们还证明了当一个凸体存在且凸时,它与欧氏球的k-相交体的Banach-Mazur距离有界于一个仅依赖于k的常数,推广了Hensley和Borell的一个著名结果.最后,我们给出了一些体积估计k-相交机构。

英文摘要:

We study isomorphic properties of two generalizations of intersection bodies, the class of k-intersection bodies and the class of generalized k-intersection bodies. We also show that the Banach-Mazur distance of the k-intersection body of a convex body, when it exists and it is convex, with the Euclidean ball, is bounded by a constant depending only on k, generalizing a well-known result of Hensley and Borell. We conclude by giving some volumetric estimates for k-intersection bodies.
