Paraproducts in one and several parameters
Paraproducts in one and several parameters
Here, 1/p + 1/q = 1/r and special attention is paid to the case of 0 < r < 1. (Note that the families of multiparameter paraproducts are much richer than in the one parameter case.) These estimates are the essential step in the version of the multiparameter Coifman-Meyer theorem …
