We give some topological properties, inclusion relations, obtain the Schauder basis and determine alpha-, beta- and gamma- duals of the spaces c(0)(T) and c(T). We characterize certain matrix classes (c(0)(T), Y) and (c(T), Y), where Y is any of the spaces c(0), c or l(infinity). Finally, using Hausdorff measure of non-compactness we characterize certain class of compact operators on the space c(0)(T).en10.11568/kjm.2021.29.1.25info:eu-repo/semantics/closedAccessTribonacci sequence spaceSchauder basisalpha-, beta-, gamma- dualsMatrix TransformationHausdorff measure of non-compactnessArticle2912540WOS:000635717200003N/A
