Weak Type Estimates for Commutators of the Marcinkiewicz Integral on Herz-Type Spaces

YANG Xiang-zheng,CHEN Dong-xiang(Institute of Mathematics and Informatics,Jiangxi Normal University,Nanchang 330022,China)  
Let μΩ be the Marcinkiewicz integral and μΩ,b the commutator generalized by μΩ and b∈Λ·β(Rn).It is proved that μΩ,b is bounded from the Herz-type Hardy space HK·n(1-1/q1)+β,pq1(Rn) into the weak Herz space WK·n(1-1/q1)+β,pq2(Rn),where 0p≤1,1q1,q2∞,1/q2=1/q1-β/n.
