摘要
讨论了集合关于基数的分解与合成,证明了基数为c的集合可分解为c个互不相交的基数为c的真子集的和集,进而证明了c个基数为c的集合的和集基数为c。
The set of disunion and union of a family of a sets about cardinal number is discussed in this paper, shows that for a set A which Cardinal number is c,there exist a family of sets Ai,such that
Where the cardinal number of all Ai and I is c. conversely fit is true.
