摘要: 完全中心Delannoy数可以由Delannoy三角形或格路的计数定义,通过利用Riordan矩阵的A-矩阵得到了几类格路计数的Riordan矩阵表达式. 给出了完全中心Delannoy数的几类组合解释,并证明了这些矩阵与完全中心Delannoy数之间相互联系.

关键词: 格路, Riordan矩阵, A-矩阵, 完全中心Delannoy数

Abstract: The complete central Delannoy number can be defined by Delannoy triangle or counting of lattice path. By using A-matrix of Riordan matrix, the Riordan matrix expressions of several lattice paths are derived. Several combinatorial explanations of the complete central Delannoy numbers are given and the relationship between these matrices and the complete central Delannoy number is also considered.

Key words: Lattice path, Riordan matrix, A-matrix, the complete central Delannoy number
