| 英文摘要: |
| This paper studies the issues about the generalized inverses of tensors under the
C-product. The aim of this paper is fourfold. Firstly, this paper presents the definition of
the Moore-Penrose inverse, Drazin inverse of tensors under the C-product. Moreover, the
inverse along a tensor is also introduced. Secondly, this paper gives some other expressions
of the generalized inverses of tensors by using several decomposition forms of tensors. In
addition, the algorithms for computing the Moore-Penrose inverse, Drazin inverse of tensors
and the inverse along a tensor are established. Finally, the application of group inverse of
tensor to Markov chains is given. |
