• ### On the New Type Almost Sequence Space

Ziyattin TAŞ, Zarife ZARARSIZ

Abstract: In this paper, we introduce trf sequence spaces by means of the matrix domain of B(r, s, t) triple band matrix and fT defined by Zararsız [9]. Furthermore, we determine β– and γ– duals of the space trf and characterize the classes (trf : l), (trf : c), (l : trf) and (c : trf).

Keywords: Almost convergence, β– and γ– duals, matrix domain of a sequence space, isomorphism.
