THE χγ2F − SUMMABLE SEQUENCES OF STRONGLY FUZZY NUMBERS

Yıl 2011, Cilt: 01 Sayı: 1, 98 - 108, 01.06.2011

Öz

We introduce the classes of χ 2F λ A, p − summable sequences of strongly fuzzy numbers and give some relations between these classes. We also give a natural relationship between χ 2F λ − summable sequences of strongly fuzzy numbers and strongly χ 2F λ A − statistical convergence of sequences of fuzzy numbers.
