On the Sequence Spaces of Interval Numbers

Abstract

In recent years, mathematical structures were altered with fuzzy numbers or interval numbers and these mathematical structures have been very popular in mathematics world so we have taken courage and hope from it, and we defined bounded and convergent sequences spaces of interval numbers. The purpose of this paper is to introduce the null, convergent and bounded sequence spaces of interval numbers c i, c i and l i, respectively, consisting of all sequences x = (xk) such that (xk) is a sequence of interval numbers. Also some new defin- itions and theorems about sequence spaces of the interval numbers were given in this paper.
