Anisotropic flows without global terms and dual Orlicz Christoffel-Minkowski type problem

Shanwei Ding, Guanghan Li

Abstract

In this paper, we study the long-time existence and asymptotic behavior for a class of anisotropic non-homogeneous curvature flows without global forcing terms. By the stationary solutions of such anisotropic flows, we obtain existence results for a class of dual Orlicz Christoffel-Minkowski type problems, which is equivalent to solve the PDE $G(x,u_K,Du_K)F(D^2u_K+u_KI)=1$ on $\mathbb S^n$ for a convex body $K$, where $D$ is the covariant derivative with respect to the standard metric on $\mathbb S^n$ and $I$ is the unit matrix of order $n$. This result covers many previous known solutions to $L^p$ dual Minkowski problem, $L^p$ dual Christoffel-Minkowski problem, and some dual Orlicz Minkowski problem etc.. Meanwhile, the variational formula of some modified quermassintegrals and the corresponding prescribed area measure problem (Orlicz Christoffel-Minkowski type problem) are considered, and inequalities involving modified quermassintegrals are also derived. As corollary, this gives a partial answer about the general prescribed curvature problem raised in Guan-Ren-Wang (CPAM, 2015).

Key Result

Theorem 1.2

Let $F\in C^2(\Gamma_+)\cap C^0(\partial\Gamma_+)$ satisfy Assumption a1.1, and let $M_0$ be a closed, smooth, uniformly convex hypersurface in $\mathbb{R}^{n+1}$, $n\geqslant2$, enclosing the origin. Suppose $(i)$$\lim\sup_{s\rightarrow+\infty}[\max_{y=sx}G(x,y)s^\beta]<1<\lim\inf_{s\rightarrow0^+}
