摘要

引入Hilbert C * -模上C *值半线性形式对应的b样条插值问题，研究其基本性质及其解的唯一性。我们首先研究了Hilbert C *模是自对偶的情况下的问题。传递到Hilbert W * -模的集合，我们通过刻画扩展C *值半线性形式的样条插值问题何时有解来给出我们的主要结果。最后，广泛讨论了W *代数的C *理想上Hilbert C * -模的b样条插值问题的解。

B-spline interpolation problem in Hilbert C∗-modules

We introduce the B-spline interpolation problem corresponding to a C∗-valued sesquilinear form on a Hilbert C∗-module and study its basic properties as well as the uniqueness of solution. We first study the problem in the case when the Hilbert C∗-module is self-dual. Passing to the setting of Hilbert W∗-modules, we present our main result by characterizing when the spline interpolation problem for the extended C∗-valued sesquilinear form has a solution. Finally, solutions of the B-spline interpolation problem for Hilbert C∗-modules over C∗-ideals of W∗-algebras are extensively discussed.
