摘要：We prove the necessary and sufficient conditions for an infinity
matrix to be a mapping, from absolutely convergent series to
convergent sequences, which is treated as general weighted mean
summability methods. The results include a classical result by
Hardy and another by Moricz and Rhoades as particular cases.
