Compact Operators on Matrix Domains via the Hausdorff Measure of Non-Compactness

Mohammed Abdullahi & Ahmadu Kiltho DOI: 10.5281/zenodo.22332083 SSR Journal of Multidisciplinary (SSRJM) This paper gives a quantitative compactness framework for operators on matrix domains of triangular matrices. Let XA={x:Ax∈X} be equipped with the natural norm induced by an invertible triangle Read More …
