Abstract:We present an iterative method based on repeatedly inverting the Monge-Ampère operator with Dirichlet boundary condition and prescribed right-hand side on a bounded, convex domain . We prove that the iterates generated by this method converge as to a solution of the Monge-Ampère eigenvalue problem
Since the solutions of this problem are unique up to a positive multiplicative constant, the normalized iterates converge to the eigenfunction of unit height. In addition, we show that , where the Rayleigh quotient is defined as
Our method converges for a wide class of initial choices that can be constructed explicitly, and does not rely on prior knowledge of the Monge-Ampère eigenvalue .

Monge–Ampère特征值问题的逆迭代
摘要:我们提出了一种基于Dirichlet边界条件并在有界凸域上规定了右手边的Monge-Ampère算子反复求逆的迭代方法。我们证明了该方法生成的迭代收敛到Monge-Ampère特征值问题的解
由于此问题的解决方案在一个正的乘法常数之前都是唯一的,因此归一化的迭代收敛到单位高度的本征函数。此外,我们证明,其中瑞利商定义为
我们的方法适用于可以明确构造的多种初始选择,并且不依赖于对Monge-Ampère特征值的先验知识。
