Measures of Noncompactness in Summable Sequence Spaces
arXiv:1805.03960
Abstract
In this paper we first define the summable sequence spaces and obtain some basic results related to these spaces. The necessary and sufficient conditions for infinite matrices to map these spaces on is obtained and Hausdorff measure of noncompactness is then used to obtain the necessary and sufficient conditions for the compactness of linear operators defined on these spaces.
