Weighted boundedness of Hardy and P\'{o}lya-Knopp type operators with variable limits on product space

Abstract

We characterize the sufficient conditions which three weight functions $u$ and $v_{1}, v_{2}$ satisfy ensure the boundedness of the Hardy operator with variable limits on product space. The corresponding bound is explicitly worked out. Moreover, as application, we can obtain an explicit scale of bound for the P\'{o}lya-Knopp type operator with certain weights.
