该文研究Hopf代数的结构常数.首先,引入高维矩阵,并用高维矩阵刻画结合代数的结构常数.其次,在余代数中,引入结构常数的概念,并用高维矩阵来描述.还给出了预余代数成为余代数,以及预双代数成为双代数和Hopf代数的条件.
The concept of structure constants for Hopf algebras is introduced and studied in this paper. Higher dimensional matrices are introduced to describe the structure constants for Hopf algebras. The condition for a precoalgebra to be a coalgebra and the condition for a pre- bialgebra to be a bialgebra and a Hopf algebra are determined in form of higher dimensional matrices.
