基于缩减和增广的边界Nevanlinna-Pick插值

Boundary Nevanlinna-Pick interpolation via reduction and augmentation

Jim Agler, N. J. Young

摘要:

给出了具有边界插值节点和边界目标值的Nevanlinna-Pick问题的Sarason可解性判据的初等证明。我们也给出了这样的问题的所有解决方案的具体参数化。证明是基于一个减少的方法,由于朱莉娅和Nevanlinna。减少功能对应于Schur互补的相应的挑选矩阵。

英文摘要:

We give an elementary proof of Sarason's solvability criterion for the Nevanlinna-Pick problem with boundary interpolation nodes and boundary target values. We also give a concrete parametrization of all solutions of such a problem. The proofs are based on a reduction method due to Julia and Nevanlinna. Reduction of functions corresponds to Schur complementation of the corresponding Pick matrices.
