建立集合族空间,讨论了公共元的通有稳定性,得到了闭集族空间上的交运算在Hausdorff拓扑下的上半连续性,并研究了不动点、Fan Ky点的通有稳定性.
A family-of-set space is established. And its common elements' generic stability is studied. The upper semi-continuity of operation of sets' intersection in family-of-closed-set space is obtained. And generic stability of fixed point and Fan Ky point is studied.
