Boundedness and norm of certain p-adic Hardy-Littlewood-Pólya-type operators (2505.09335v5)

Abstract: In this paper, by introducing some parameters, we define and study certain $p$-adic Hardy-Littlewood-P\'{o}lya-type integral operators acting on $p$-adic weighted Lebesgue spaces. We completely characterize the boundedness of these operators in terms of the parameters. For some special cases, we obtain sharp norm estimates for the operators. These results are not only a complement to some previous results but also an extension of existing ones in the literature.
