This lecture is based on a joint work with Jean Bourgain. I will
present new estimates for the Laplacian, for the div -curl system,
for circulation integrals, and for more general integrals of
differential forms in arbitrary dimension N. By duality they yield
new results concerning the decomposition of vector-fields in the
critical Sobolev space W^(1,N).
