A Note on Lattice Paths with Diagonal Steps in Three-Dimensional Space
1
作者 卢青林 《Journal of Mathematical Research and Exposition》 CSCD 北大核心 2005年第3期447-450,共4页
Jr. Stocks[4] discussed lattice paths from (0, 0, 0) to (n, n, n) with diagonal steps under some restrictions. In this note, we give simpler formulas for the main results in [4], andextend them to a general case.
关键词 lattice path diagonal step andre's reflection principle.
