Abstract :
Abstract. In this paper we first introduce N¯ q∆ summable difference summable difference these sequence spaces on the spaces c, c and . Finally, the Hausdorff0 ∞
measure of noncompactness is used to obtain the necessary and suffi-cient conditions for the compactness of the linear operators defined on these spaces.
