AI总结:

本文研究C-相容集的$L_p$对偶Minkowski问题,推导无界凸超曲面的新型Monge-Ampère方程,分别在C-确定集族与$(C,p,q)$-接近集族中求解该问题,并得到$p\leq q$时的解唯一性结果。

摘要:

本文核心研究对象是C-相容集的$L_p$对偶Minkowski问题,其中C是$\u211d^n$中具有非空内部的点式闭凸锥。该问题旨在刻画C-相容集的$(p,q)$阶对偶曲率测度,推导出针对无界凸超曲面的新型Monge-Ampère方程,这类方程通常定义在开区域上,且未知凸函数非正。在C-确定集族中,对$0\neq p\in\u211d$且$q\in\u211d$的情形求解了$L_p$对偶Minkowski问题;在新定义的$(C,p,q)$-接近集族中,对$p\leq0$且$p<q$的范围求解了该问题。当$p\leq q$时,还得到了C-相容集的$L_p$对偶Minkowski问题解的若干唯一性结果。

英文摘要:

The central focus of this paper is the $L_p$ dual Minkowski problem for $C$-compatible sets, where $C$ is a pointed closed convex cone in $\mathbb{R}^n$ with nonempty interior. Such a problem deals with the characterization of the $(p, q)$-th dual curvature measure of a $C$-compatible set. It produces new Monge-Ampère equations for unbounded convex hypersurface, often defined over open domains and with non-positive unknown convex functions. Within the family of $C$-determined sets, the $L_p$ dual Minkowski problem is solved for $0\neq p\in \mathbb{R}$ and $q\in \mathbb{R}$; while it is solved for the range of $p\leq 0$ and $p<q$ within the newly defined family of $(C, p, q)$-close sets. When $p\leq q$, we also obtain some results regarding the uniqueness of solutions to the $L_p$ dual Minkowski problem for $C$-compatible sets.
