摘要:

在本文中,我们有兴趣发展张量结构中的迭代Krylov子空间方法来解决一类多线性方程组的Einstein乘积。特别是,我们开发的GMRES和Gloub-Kahan双对角化过程的张量框架中的全球变种。进一步考虑了该方程可能对应于一个离散不适定问题的情形。应用所产生的彩色图像和视频恢复。

英文摘要:

In the present paper, we are interested in developing iterative Krylov subspace methods in tensor structure to solve a class of multilinear systems via Einstein product. In particular, we develop global variants of the GMRES and Gloub--Kahan bidiagonalization processes in tensor framework. We further consider the case that mentioned equation may be possibly corresponds to a discrete ill-posed problem. Applications arising from color image and video restoration are included.
