关于凸体的截面和投影的不等式

Inequalities for sections and projections of convex bodies

Apostolos Giannopoulos, Alexander Koldobsky, Artem Zvavitch

摘要:

这篇文章属于几何层析成像领域,它是基于关于它们的截面和投影的数据来研究固体的几何性质。我们描述了一个新的方向,在几何层析成像中,不同的体积结果被认为是在一个更一般的设置,与体积取代的任意措施。令人惊讶的是,这种通用方法适用于许多体积结果。特别地,我们讨论了任意测度下凸体截面上的Busemann-Petty问题和任意测度下的切片问题。我们目前的情况下,这些问题的一般化功能。一些概括的问题有关的预测,如Shephard的问题,也讨论了以及在离散层析成像的一些问题。

英文摘要:

This article belongs to the area of geometric tomography, which is the study of geometric properties of solids based on data about their sections and projections. We describe a new direction in geometric tomography where different volumetric results are considered in a more general setting, with volume replaced by an arbitrary measure. Surprisingly, such a general approach works for a number of volumetric results. In particular, we discuss the Busemann-Petty problem on sections of convex bodies for arbitrary measures and the slicing problem for arbitrary measures. We present generalizations of these questions to the case of functions. A number of generalizations of questions related to projections, such as the problem of Shephard, are also discussed as well as some questions in discrete tomography.
