论文摘要
如果POSET的每个主要秩序过滤器对整个Poset都是同构的，则称为POSET的上部同质（或“ Upho”）。我们观察到，Upho Posets的等级和特征生成函数是彼此的乘法逆。
A poset is called upper homogeneous (or "upho") if every principal order filter of the poset is isomorphic to the whole poset. We observe that the rank and characteristic generating functions of upho posets are multiplicative inverses of one another.
