Approximation of fuzzy numbers by convolution method
Huan Huang, Congxin Wu
In this paper we consider how to use the convolution method to construct approximations, which consist of fuzzy numbers sequences with good properties, for a general fuzzy number.…

Some notes on characterizations of compact sets in fuzzy number spaces
Huan Huang, Congxin Wu
In this paper, we presents a characterization of compact subsets of the fuzzy number space equipped with the level convergence topology. Based on this, it is shown that compactness…
