We give the L-p-boundedness for a class of Marcinkiewicz integral operators
mu (Omega), mu (Omega)*,lambda and mu (Omega),s related to the Littlewood-
Paley g-function, g(lambda)*-function and the area integral S, respectively
. These operators have the kernel functions Omega is an element of H-1(Sn-1
), the Hardy space on Sn-1. The results in this paper substantially improve
and extend the known results.
