In this paper, we discuss isomorphic factorization for tensor product of two pisible graphs and prove the conditions for the tensor product graphs to be factorized isomorphically.
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 order to research the isomorphism problem of certain graphs,we defineK-pisive graphs and K-standard standard graphs,and research the structure and property of 1-pisive graphs.
作者研究一类图的同构问题,给出了K-可区分图及K-标准图的定义〔0
On the basis of studying the enumeration problems for unlabeled graphs,the definition of subpisible graphs is introduced.
在研究若干图族其计数问题的基础上,提出了可分割图族的概念,进而利用组合的方法,建立了求解可分割图族计数问题的一般公式。
