Fuzzy集的势与可数Fuzzy基数 总被引:2,自引:0,他引:2
本文首先定义了Fuzzy集的等势关系和Fuzzy集的势,并讨论了有关Fuzzy集的势的若干命题,然后在自然数集上定义了可数Fuzzy基数。最后给出了确定可数论域上Fuzzy集的Fuzzy基数的方法,并对其若干性质进行了讨论。上述定义均以经典集论中相应定义为特款。 相似文献

Let F be an arbitrary family of subsets of U and f be a mapping: F→{0,1}, how can we tell whether fz=f for some subset Z of U and how can we construct this Z (or the equivalence class of such Zs)? Here fz:?T∈F,(?).This problem was recognized by D. G. Kendall and the largest element of such Z' s had been established at the same time. In this paper, we shall obtain a class of the minimums and a complete consequence of such Z's by means of F-atom, contacta-bility and relation equation. 相似文献
