标题： A note on delay-inverse systems, I

摘要： 最近引入了范畴中逆系统的广义概念，以及相应的pro-范畴的概念。这些所谓的延迟逆系统和延迟pro-范畴有可能产生新的（延迟）逆系统理论，以及一种更粗略的抽象形状理论。 然而，我们已经证明，只要索引集的势为$\aleph_{n}, n\in\mathbb{N}_{0}$，这种潜在的新理论在本质（分类和不变量）上就退化为普通理论。 显示英文摘要

摘要： A generalization of an inverse system in a category was recently introduced, as well as that of the corresponding pro-category These so called the delay-inverse systems and delay-pro-category could potentially yield a new theory of (delay-) inverse systems as well as a kind of coarser abstract shape theory. However, we have proven that, whenever an indexing set has cardinality $\aleph_{n}, n\in\mathbb{N}_{0}$, the potential new theory reduces, in its essence (the classification and invariants), to the ordinary one.
