本文讨论了两个可分图的张量乘积图的同构因子分解问题。

In this paper, we discuss isomorphic factorization for tensor product of two divisible graphs and prove the conditions for the tensor product graphs to be factorized isomorphically.

通过把高阶张量写成若干逆变和协变矢量的乘积，直接从变换入手，给出了定义高阶张量协变导数的另一种方法。

This paper discusses another way, which is rewritten as product of a few contravariant vectors and covariant vectors, to define higher order tensors covariant derivative through transformations.
