论文摘要
在本文中,我们研究了某些由$ 2 $ posets $ 2 $类别中的宽松的链条构成的晶格中的最大链。这样的研究是由于在较低的维度中,我们得到了一些熟悉的组合物体,例如Dyck Paths和Kreweras Walks。
In this paper we study maximal chains in certain lattices constructed from powers of chains by iterated lax colimits in the $2$-category of posets. Such a study is motivated by the fact that in lower dimensions, we get some familiar combinatorial objects such as Dyck paths and Kreweras walks.
