초록

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.
