In
this study, it is defined almost sequence spaces f(Λ ̂ ), f_0(Λ ̂ ) and fs(Λ ̂ ) as domain of the
matrix . ∆_u^λ Some topological
properties of these spaces are investigated and determined β-,  γ- duals of aforementioned sequence space. Futhermore, it is
characterized the class of matrices (f(Λ ̂ ): μ), (fs(Λ ̂ ):μ),( μ:f(Λ ̂ )) and  ( μ:fs(Λ ̂), where μ is any given
sequence space. 

Anahtar Kelimeler

Almost convergent, dual spaces, matrix transformations, matrix domain of a sequence space, sequence spaces
