Abstract

The class of Muckenhoupt weights has been extended to the multilinear setting in several contexts of real and Fourier analysis. In this work, we provide new characterizations of these multilinear weight classes through a unifying principle based on pointwise, rather than averaged, evaluation of the weights.
