摘要
考虑具有四种步型的格路,称之为加权广义的Schroder路.利用Riordan矩阵研究了加权广义Schroder路的计数问题,得到了Schroder数几种新的组合解释.
In this paper,we consider lattice paths with four types of steps,which are called weighted generalized Schroder paths.Using Riordan array method,we study some of enumerations of weighted generalized Schroder paths,and get several new combinatorial interpretations of Schroder numbers.
