Narayana数相关恒等式的证明

Proof of Identities of Narayana Numbers

从Narayana数的Dyck路的组合背景出发,结合点的坐标,建立了Dyck路之间一种新的一一对应,给出了与其有关的一些恒等式的组合证明,同时把发生函数的思想用到对相关恒等式的研究中。

A newbijection between Dyck paths is founded by the combined background of Narayana numbers and the coordinate. So the combinatorial proof of the identities are given.And the thought of generating function is applied to study of these identities.
