On Cauchy sequences in a fuzzy-valued metric space

Salih Aytar


We introduce the concept of Cauchy sequence of fuzzy numbers in the fuzzy metric space of fuzzy numbers by using more positive fuzzy numbers, instead of just the positive characteristic functions used in Guangquan's definition. Then we compare this definition with the definition of Cauchy sequence in the real valued supremum metric.


Fuzzy number; Fuzzy metric space; Cauchy sequence.
