In this paper, the authors study the boundedness of the Marcinkiewicz integ
ral mu(Omega) on BMO(R-n) and the Campanato spaces E-alpha,E-p(R-n). Here O
mega is homogeneous of degree zero satisfying a class of L-q-Dini condition
s. The results in this paper are a substantial improvement of some known re
sults. (C) 2000 Academic Press.
