Duals and matrix classes involving Cesàro type classes of sequences of fuzzy numbers. (English) Zbl 1409.40001

Summary: We first define Cesàro type classes of sequences of fuzzy numbers and equip the set with a complete metric. Then we compute the Köthe-Toeplitz dual and characterize some related matrix classes involving such classes of sequences of fuzzy numbers.
