摘要:
本文关注两类D不变多项式子空间。第一类是经典类型,第二类是新类。通过矩阵计算,我们证明每个理想投影算子,其每个D不变子空间属于第一类或第二类,是拉格朗日投影算子的逐点极限。这验证了C. de Boor猜想的一个特例,该猜想断言每个复理想投影算子是拉格朗日投影算子的逐点极限。具体地,我们给出了此类理想投影算子的具体扰动过程。
英文摘要:
In this paper, we focus on two classes of D-invariant polynomial subspaces. The first is a classical type, while the second is a new class. With matrix computation, we prove that every ideal projector with each D-invariant subspace belonging to either the first class or the second is the pointwise limit of Lagrange projectors. This verifies a particular case of a C. de Boor's conjecture asserting that every complex ideal projector is the pointwise limit of Lagrange projectors. Specifically, we provide the concrete perturbation procedure for ideal projectors of this type.
