摘要:

在[Calc. Var., 57:5 (2018)]中,Hong-Ye-Zhang提出了p-容Orlicz-Minkowski问题,并通过变分方法证明了当p∈(1,n)时该问题凸解的存在性。然而,解的光滑性与唯一性仍是未解难题。注意到在光滑情形下,p-容Orlicz-Minkowski问题可等价转化为Monge-Ampère型方程:fϕ(h_K)|∇Ψ|^p=τG,其中p∈(1,n)且某常数τ>0,f是定义在单位球面S^{n-1}上的正函数,ϕ是定义在(0,+∞)上的连续正函数,G为高斯曲率。本文首次通过一类逆高斯曲率流,证明了当p∈(1,n)时该问题光滑解的存在性,该流光滑收敛至方程的解。此外,我们在特殊情形下证明了该方程的唯一性结果。

英文摘要:

In [Calc. Var., 57:5 (2018)], Hong-Ye-Zhang proposed the $p$-capacitary Orlicz-Minkowski problem and proved the existence of convex solutions to this problem by variational method for $p\in(1,n)$. However, the smoothness and uniqueness of solutions are still open. Notice that the $p$-capacitary Orlicz-Minkowski problem can be converted equivalently to a Monge-Ampère type equation in smooth case: \begin{align}\label{0.1} fϕ(h_K)|\nablaΨ|^p=τG \end{align} for $p\in(1,n)$ and some constant $τ>0$, where $f$ is a positive function defined on the unit sphere $\mathcal{S}^{n-1}$, $ϕ$ is a continuous positive function defined in $(0,+\infty)$, and $G$ is the Gauss curvature. In this paper, we confirm the existence of smooth solutions to $p$-capacitary Orlicz-Minkowski problem with $p\in(1,n)$ for the first time by a class of inverse Gauss curvature flows, which converges smoothly to the solution of Equation (\ref{0.1}). Furthermore, we prove the uniqueness result for Equation (\ref{0.1}) in a special case.
