Abstract
We prove some weighted estimates for two kinds of Littlewood–Paley operators related to the Riesz potentials, which can be used to characterize the weighted Sobolev spaces. Also, we show the boundedness from the weighted Hardy space $H^{1}_{w}$ to the weighted weak $L^{1}$ space of a Littlewood–Paley operator arising from spherical means.
