摘要

We establish a necessary and sufficient condition on weight functions for the boundedness of the discrete Hardy operator on weighted Musielak-Orlicz sequence spaces. In particular, we get similar results for the dual operator of the discrete Hardy operator. We give sufficient pointwise conditions on generalized Φ-functions that guarantee continuous embeddings between weighted Musielak-Orlicz sequence spaces. The results are illustrated by a number of corollaries.
