Abstract
Let X be a space of homogeneous type in the sense of Coifman and Weiss. In this paper, we prove boundedness of singular and fractional integral operators on Campanato spaces over X with variable growth conditions. The function spaces contain generalized Lipschitz spaces with variable exponent as special cases. Moreover, by using the function spaces, we can deal with functions which are L p-functions locally on one subset in X, BMO-functions locally on one another subset and Lip α -functions locally on the other one. Our results are new even for ℝn case.
