摘要:

刘维斯基问题在凸几何中涉及证明给定的单位球上的Borel测度(可能乘以常数)是凸体的某种表面积测度。特别关注 $L^p$ 刘维斯基问题和带权刘维斯基问题。本文考虑 $L^p$ 设定下的带权表面积,提出超越高斯设定的框架,通过旋转对称测度,借鉴最近的加纳德-兹瓦奇不等式发展。结果包括对于所有 $p \in \mathbb R$ 的存在性(某些情况下有对称性假设),以及在 $p \geq 1$ 下的唯一性(在凹性假设下)。最后,通过度论在所谓的“小质量区域”中获得结果,如高斯情况中由(黄、希和赵)所启发。

英文摘要:

The Minkowski problem in convex geometry concerns showing that a given Borel measure on the unit sphere is, up to perhaps a constant, some type of surface area measure of a convex body. Two types of Minkowski problems in particular are an active area of research: $L^p$ Minkowski problems, introduced by Lutwak and (Lutwak, Yang, and Zhang), and weighted Minkowski problems, introduced by Livshyts. For the latter, the Gaussian Minkowski problem, whose primary investigators were (Huang, Xi and Zhao), is the most prevalent. In this work, we consider weighted surface area in the $L^p$ setting. We propose a framework going beyond the Gaussian setting by focusing on rotationally invariant measures, mirroring the recent development of the Gardner-Zvavitch inequality for rotationally invariant, log-concave measures. Our results include existence for all $p \in \mathbb R$ (with symmetry assumptions in certain instances). We also have uniqueness for $p \geq 1$ under a concavity assumption. Finally, we obtain results in the so-called "small mass regime" using degree theory, as instigated in the Gaussian case by (Huang, Xi and Zhao).
