Resumen de Maximal functions, product condition and its eccentricity

We characterize Muckenhoupt A^p weights in the product case on {\mathbb{R}^N} in terms of a graded family of A^p conditions defined by rectangles with a lower bound on eccentricity. The connection to maximal functions and geometric coverings is also studied.
