Query: Endpoint for the div-curl lemma in Hardy spaces   We give a div-curl type lemma for the wedge product of closed differential
forms on R^n when they have coefficients respectively in a Hardy space and
L^infinity or BMO. In this last case, the wedge product belongs to an
appropriate Hardy-Orlicz space.
