A Class of Commutators for Multilinear Fractional Integrals in Nonhomogeneous Spaces

Let [inline-graphic not available: see fulltext] be a nondoubling measure on [inline-graphic not available: see fulltext]. A class of commutators associated with multilinear fractional integrals and RBMO([inline-graphic not available: see fulltext]) functions are introduced and shown to be bounded on product of Lebesgue spaces with [inline-graphic not available: see fulltext].
