摘要
我们定义 { 我 } 反(i = 1, 2, 5 ) 并且张肌的组逆基于张肌的一个一般产品。我们在解决张肌方程和块张肌的计算公式上探索张肌的概括的逆的性质。我们使用 { 1 } 张肌的逆由张肌代表了给一个 multilinear 系统的解决方案。代表为 { 1 } 逆和一些块张肌的组逆被建立。
We define the {i}-inverse (i = 1,2, 5) and group inverse of tensors based on a general product of tensors. We explore properties of the generalized inverses of tensors on solving tensor equations and computing formulas of block tensors. We use the {1}-inverse of tensors to give the solutions of a multilinear system represented by tensors. The representations for the {1}-inverse and group inverse of some block tensors are established.
