Abstract
J. Bourgain and H. Brezis have obtained in 2002 some new and surprising estimates for systems of linear differential equations, dealing with the endpoint case L¹ of singular integral estimates and the critical Sobolev space W1,n(Rn). This paper presents an overview of the results, further developments over the last ten years and challenging open problems.
