| Résume | he L^p boundedness of commutators [b,T] = bT-Tb of pointwise multiplication b and singular integral operators T has been well studied for a long time. There are also many results about L^p to L^q boundedness for pq. I will supply the missing pieces to present a complete picture of the L^p to L^q boundedness for all finite p,q>1, and relate the regime of exponents p>q to the mapping properties of the Jacobian on first order Sobolev spaces. |
