Resumen:
We deal with the boundedness properties of higher order commutators related to somegeneralizations of the multilinear fractional integral operator of order m, Ima , from a product ofweighted Lebesgue spaces into adequate weighted Lipschitz spaces, extending some previousestimates for the linear case. Our study includes two different types of commutators and sufficientconditions on the weights in order to guarantee the continuity properties described above.We also exhibit the optimal range of the parameters involved. The optimality is understood inthe sense that the parameters defining the corresponding spaces belong to a certain region, beingthe weights trivial outside of it. We further show examples of weights for the class which coverthe mentioned area.
