The purpose of this paper is to establish some characterizations of mixed central Campanato space Cp→,λ(Rn), via the boundedness of the commutator operators of Hardy type. Unlike the case λ⩾0, there are some technical difficulties caused by λ<0 to be overcome. In addition, an extra assumption cal...
