复$k$ -Hessian泛函的Dirichlet原理

The Dirichlet principle for the complex $k$-Hessian functional

Yi Wang, Hang Xu

摘要:

研究了有界区域$X\subset \mathbb C^n$上复$k$-Hessian方程的变分结构.证明了$X$上的Dirichlet问题$σ_k (\partial \bar{\partial} u) =0$和$M$上的$u=f$是变分的,并给出了相应泛函$\mathcal{E}_k(u)$的显式构造.证明了$\mathcal{E}_k(u)$满足Dirichlet原理。在$k=2$的特殊情况下,我们构造的泛函$\mathcal{E}_2(u)$涉及边界的Hermite平均曲率,这一概念首先由X.王. J. Case和本文第一作者的早期工作为满足Dirichlet原理的(实)$k$ -Hessian泛函引入了一个边界算子。本文证明了在复杂背景下存在一个平行的图象。

英文摘要:

We study the variational structure of the complex $k$-Hessian equation on bounded domain $X\subset \mathbb C^n$ with boundary $M=\partial X$. We prove that the Dirichlet problem $σ_k (\partial \bar{\partial} u) =0$ in $X$, and $u=f$ on $M$ is variational and we give an explicit construction of the associated functional $\mathcal{E}_k(u)$. Moreover we prove $\mathcal{E}_k(u)$ satisfies the Dirichlet principle. In a special case when $k=2$, our constructed functional $\mathcal{E}_2(u)$ involves the Hermitian mean curvature of the boundary, the notion first introduced and studied by X. Wang. Earlier work of J. Case and and the first author of this article introduced a boundary operator for the (real) $k$-Hessian functional which satisfies the Dirichlet principle. The present paper shows that there is a parallel picture in the complex setting.
