考虑广义Dyck路径中半长、步数以及峰数、返回步数等可加性参数的计数问题,给出了相应的计数公式,推广了Deutsch和Coker等人的工作.
In this paper,we consider the enumeration of general Dyck paths according to semilength,number of steps and some other additive parameters,such as number of peaks and number of return steps.The counting formulas for each case are given.Our results generalize the previous work of Deutsch and Coker.
