Abstract
In this study, we define the double sequence spaces (Mu)Rqt, (Cp)Rqt, (Cbp)Rqt and (Cr)Rqt as the domain of four dimensional Riesz mean Rqt in the spaces Mu, Cp, Cbp and Cr, respectively. Then, we examine some topological properties of those sequence spaces and we characterize the RHâregularity of the Riesz mean Rqt. Taking Ïâ{p,bp,r}, we determine the β(Ï)âduals of the spaces (CÏ)Rqt and we characterize the classes ((Cr)Rqt:CÏ), (μ:(CÏ)Rqt) and ((CÏ)Rqt:Cf) of four-dimensional matrix transformations, where μ and Cf denote any given double sequence space and the space of almost convergent double sequences, respectively.
