An Abstract Coifman–rochberg–weiss Commutator Theorem

Abstract

It is a special pleasure for us to dedicate this paper to you, our dear friend Dan Waterman on the occasion of your 80th birthday. But that is not all.The things we discuss here are intimately related to important work by another dear friend, and so to you too Richard Rochberg, warmest greetings on the occasion of your 65th birthday. We wish both of you many many more wonderful and creative years.Abstract. We formulate and prove a version of the celebrated Coifman-Rochberg-Weiss commutator theorem for the real method of interpolation 1 we shall only consider the J−method in this note. 2 we use 2 for definitiness, obviously can replace 2 by 1 + ε.
