A class of commutators for multilinear fractional integrals in nonhomogeneous spaces
Let \(\mu\) be a Radon measure on \(\mathbb{R}^d\) which is not assumed to be doubling but satisfies some growth condition of exponential type. A class of commutators associated with multilinear fractional integrals and RBMO(\(\mu\)) functions is introduced. Moreover, these communicators are shown to be bounded on products of Lebesgue spaces equipped with \(\mu\). Reviewer's remark: Without having the English edited more carefully, it is hard to check the correctness of the results.
