In the continuation of study, inclusion relations, alpha, beta and gamma duals, Schauder basis and matrix mapping classes concerning these spaces are introduced. Finally, compact operators on these novel sequence spaces are characterized by the utilization of Hausdorff measure of non-compactness.eninfo:eu-repo/semantics/closedAccessOresme NumbersSequence SpacesMatrix MappingsHausdorff Measure Of Non-CompactnessCompact OperatorsArticle10.1007/s40995-024-01734-54937257322-s2.0-85208926286Q3WOS:001352550000001Q30000-0001-9420-8264
