In this talk, we investigate the limit case $p=1$ of the Stein-Weiss inequality for the Riesz potential. Our main result is a characterization of this inequality for a special class of vector fields associated to cocanceling operators. As application, we recovered some classical div-curl inequalities in literature. In addition, we also discussed a two-weight inequality with general weights extending the previous result due to Sawyer for the scalar case.

Joint work with Pablo De Nápoli (Universidad de Buenos Aires , Argentina).
