摘要:

张量广义逆是张量理论研究的重要内容之一.在近年张量广义逆研究的基础上,该文给出在爱因斯坦积下张量core逆的性质、张量偏序和张量方程 ${{\cal A}}{*}{{\cal X}}={{\cal B}}在条件{{\cal X}}∈{\Bbb{\cal R}}({{\cal A}}) $下的最小二乘解等.

关键词: core逆, 爱因斯坦积, 偏序, 张量方程

Abstract:

Tensor generalized inverse is one of the important contents of tensor theory research. In this paper, based on the research of tensor generalized inverse in recent years, we obtain some properties of the core inverse of tensor with the Einstein product, a tensor partial ordering based on the core inverse and the least-squares solution of $ {{\cal A}} {*}{{\cal X}}={{\cal B}}$ under condition ${{\cal X}}\in{\Bbb {\cal R}}({{\cal A}}) $.

Key words: Core inverse, Einstein product, Partial ordering, Tensor equation
