Resumen de A new type of difference class of interval numbers.

Achyutananda Baruah, Amar Jyoti Dutta

• In this article we introduce the notation difference operator ∆m (m ≥ 0 be an integer) for studying some properties defined with interval numbers. We introduced the classes of sequence (∆m), (∆m) and  (∆m) and investigate different algebraic properties like completeness, solidness, convergence free etc.
