Abstract : We consider the weighted spaces ℓp(S, φ) and ℓp(S, ψ), for 1 < p < +∞,
where φ and ψ are weights on S (= N or Z). We obtain a sufficient condition for ℓp(S, ψ) to be multiplier weighted-space of ℓp(S, φ) and ℓp(S, ψ).
Our condition characterizes the last multiplier weighted-space in the case
where S = Z. As a consequence, in the particular case where ψ = φ, the
weighted space ℓp(Z,ψ) is a convolutive algebra.
