摘要:

本文通过M-product引入了张量上的Drazin逆和core-EP逆的概念。我们提出了张量Drazin逆和core-EP逆的一些性质,以及计算这些逆的有效基于张量的算法。此外,在M-product框架下给出了复合广义逆的定义,包括张量的CMP、DMP和MPD逆。设计了基于张量的高阶Gauss-Seidel和Gauss-Jacobi迭代方法。开发了这两种迭代方法求解多线性方程的算法。使用Drazin逆、core-EP逆以及CMP、DMP和MPD逆等复合广义逆求解了某些多线性系统。应用基于张量M-product的正则化技术解决了彩色图像去模糊问题。

英文摘要:

This paper introduces notions of the Drazin and the core-EP inverses on tensors via M-product. We propose a few properties of the Drazin and core-EP inverses of tensors, as well as effective tensor-based algorithms for calculating these inverses. In addition, definitions of composite generalized inverses are presented in the framework of the M-product, including CMP, DMP, and MPD inverse of tensors. Tensor-based higher-order Gauss-Seidel and Gauss-Jacobi iterative methods are designed. Algorithms for these two iterative methods to solve multilinear equations are developed. Certain multilinear systems are solved using the Drazin inverse, core-EP inverses, and composite generalized inverses such as CMP, DMP, and MPD inverse. A tensor M-product-based regularization technique is applied to solve the color image deblurring.
