算子的融合框架表示

Representation of Operators Using Fusion Frames

Peter Balazs, Mitra Shamsabadi, Ali Akbar Arefijamaal, Chilles Gardon

摘要:

在许多应用中,为了求算子方程的数值解,需要在子空间中进行分解。因此,有必要将矩阵表示的已知方法扩展到融合帧的利用。本文研究了希尔伯特空间$\Hil$上算子的Bessel融合序列、融合框架和Riesz分解的表示.我们将给出基本定义。我们将展示一些结构结果并给出一些例子。此外,在Riesz分解的情况下,我们证明了这些功能是同构。此外,我们还想找到这种矩阵表示的伪逆和逆(如果存在)。我们将把这个思想应用到Schatten $p$ -类算子上。最后,我们证明了融合框架的张量是Hilbert-Schmidt算子空间中的框架。

英文摘要:

For finding the numerical solution of operator equations in many applications a decomposition in subspaces is needed. Therefore, it is necessary to extend the known method of matrix representation to the utilization of fusion frames. In this paper we investigate this representation of operators on a Hilbert space $\Hil$ with Bessel fusion sequences, fusion frame and Riesz decompositions. We will give the basic definitions. We will show some structural results and give some examples. Furthermore, in the case of Riesz decompositions, we prove that those functions are isomorphisms. Also, we want to find the pseudo-inverse and the inverse (if there exists) of such matrix representations. We are going to apply this idea to the Schatten $p$-class operators. Finally, we show that tensors of fusion frame are frames in the space of Hilbert-Schmidt operators.
