摘要
研究模糊数序列{un}关于上确界度量,Skorohod度量,Lp型度量(1≤p<∞)的收敛与水平收敛之间的关系。证明了:如果模糊数序列{un}的极限u是连续模糊数,那么模糊数序列{un}关于上述的四种收敛是等价的。
The aim is to study the relationship between convergences of sequences of fuzzy numbers with respect to the supremum metric, Skorohod metric, Lp metric ( 1 ≤p 〈 ∞ ), and the level convergence. It is shown that if the limit u of sequences { un} of fuzzy numbers is a continuous fuzzy number, then all the previous convergences are equivalent.
