Hessian eigenvalue的谱特征和逼近格式

A spectral characterization and an approximation scheme for the Hessian eigenvalue

Nam Q. Le

摘要:

我们重新审视了$\mathbb R^n$中光滑、有界、$k$-凸区域上的$k$ -Hessian本征值问题。首先,我们得到了系数属于相应Garding锥对偶的线性二阶椭圆算子的第一特征值的下确界为$k$ -Hessian特征值的谱刻画.其次,我们引入了一个非退化的逆迭代格式来求解$k$ -Hessian算子的本征值问题。我们表明,该计划收敛,速率,所有$k$的$k$ -海森特征值。当采用$2\leq k\leq n$时,我们还证明了该格式解的Hessian的局部$L^1$收敛性.双曲多项式在我们的分析中起着重要的作用。

英文摘要:

We revisit the $k$-Hessian eigenvalue problem on a smooth, bounded, $(k-1)$-convex domain in $\mathbb R^n$. First, we obtain a spectral characterization of the $k$-Hessian eigenvalue as the infimum of the first eigenvalues of linear second-order elliptic operators whose coefficients belong to the dual of the corresponding Gårding cone. Second, we introduce a non-degenerate inverse iterative scheme to solve the eigenvalue problem for the $k$-Hessian operator. We show that the scheme converges, with a rate, to the $k$-Hessian eigenvalue for all $k$. When $2\leq k\leq n$, we also prove a local $L^1$ convergence of the Hessian of solutions of the scheme. Hyperbolic polynomials play an important role in our analysis.
