Abstract :Following Altay and Ba¸sar [1], we define the duality relation of the new sort between a pair of infinite matrices. Our focus is to study the composite dual summability methods of the new sort and to give some inclusion theorems.
Keywords : Dual summability methods, sequence spaces, matrix transformations, composition of summability methods, inclusion theorems
