In this paper define the spaces l(Δ), c(Δ), and c0(Δ), where for instance l(Δ) = {x=(xk):supk |xk -xk + l|< ∞}, and compute their duals (continuous dual, α-dual, β-dual and γ-dual). We also determine necessary and sufficient conditions for a matrix A to map l(Δ) or c(Δ) into l or c, and investigate related questions.
