论文摘要
我们在中央delannoy $ n $ paths之间展示了两者之间的培训，即从原点到$（n，n）$的晶格路径，带有步骤$ e =（1,0），\，\，n =（0,1），\，\，d =（1,1）$，以及从原点到$（n+1，n）$的晶格路径，这些阶段是限制的，他们只限制了这些步骤。
We exhibit a bijection between central Delannoy $n$-paths, that is, lattice paths from the origin to $(n,n)$ with steps $E=(1,0), \,N=(0,1),\,D=(1,1)$ and the lattice paths from the origin to $(n+1,n)$ where the only restriction on the steps is that they have finite nonnegative slope.
