Weighted weak-type iterated Hardy-Copson inequalities (Q6607800)

Certain weighted weak-type iterated Hardy inequalities have been characterized by the authors in \textit{V. García García} and \textit{P. Ortega Salvador} [J. Math. Anal. Appl. 525, No. 2, Article ID 127284, 15 p. (2023; Zbl 1547.26030)] and \textit{V. García García} and \textit{P. Ortega Salvador} [Ann. Funct. Anal. 15, No. 2, Paper No. 26, 27 p. (2024; Zbl 07825640) Article no. 26]. That work represents a natural extension of the theory of weighted strong-type iterated Hardy inequalities that has been developed in last years. In this paper the authors characterize some weighted weak-type iterated Hardy-Copson inequalities. They characterize the suitable weights for which these inequalities hold. In the proofs of the theorems the classical results on weighted strong-type inequalities for the Copson operator are used.
