✦ Synopsis
We study the relationship between Schechter's methods of complex interpolation and the so called commutator estimates. We obtain new commutator theorems and prove characterizations of the Domain and Range spaces associated with the corresponding quasilogarithmic operator. Our methods also provide a new approach to known results, including the higher order commutator theorems for the complex method recently obtained by R. ROCHBERG.

Let m be a measurable bounded function and let us assume that there exists a bounded functions S so that mðxÞSðxÞ itÀ1 is a Fourier multiplier on L p uniformly in tAR: Then, using the analytic interpolation theorem of Stein, one can show that necessarily m is a L p multiplier. The purpose of this wo
## Abstract The aim of this note is to show how all the commutator estimates of two recent papers, by M. Cwikel, N. Kalton, M. Milman, and R. Rochberg and by N. Krugljak and M. Milman, can be considered as special cases of the method of couples of interpolators introduced by M. J. Carro, J. Cerdà a
A general family of interpolation methods is introduced which includes, as special cases, the real and complex methods and also the so-called AE or G 1 and G 2 methods defined by Peetre and Gustavsson-Peetre. Derivation operators O and translation operators R are introduced for all methods of this f
