摘要
本文研究了自然数分拆的内在结构,主要讨论了序((ω),≤)和((ω),)的可分裂性,以及格((ω),≤)和((ω),)的可分配性,最后证明一个结论.
In this paper, the intrinsic structure o{ the partition of co, the separativity of the orders (( ω), ≤ and ( (ω ) ;≡) are investigated, and the distributivity of the lattices ( (ω), ≤ and ( ( ω ) ; ≡) are discussed. In the end, we prove a result related to atlas when F is a maco with at least two infinite pieces.
