Cluster points of sequences of fuzzy real numbers.(English)Zbl 1200.40002

Summary: Properties of cluster points of sequences of fuzzy real numbers are investigated. It is shown that some similar theorems like in the case of real sequences hold. On the other hand, some differences from the real case are discussed.
