Abstract : This note is devoted to establishing the boundedness for some classes of Littlewood-Paley square operators defined by the kernels without any regularity on the mixed radial-angular spaces. The corresponding vector-valued versions are also presented. As applications, the corresponding results for the Littlewood-Paley $g_{\lambda}^{*}$ function and the Littlewood-Paley function related to the area integrals are also obtained.
Keywords : Littlewood-Paley function, weighted norm inequality, mixed radial-angular space
