Keywords:
Hardy inequality; modular inequality; weight functions
Summary:
If $P$ is the Hardy averaging operator - or some of its generalizations, then weighted modular inequalities of the form \int u \phi(Pf) \leq C\int v \phi(f) are established for a general class of functions $\phi$. Modular inequalities for the two- and higher dimensional Hardy averaging operator are also given.
