Abstract :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. 
Keywords : Almost convergent, dual spaces, matrix transformations, matrix domain of a sequence space, sequence spaces
