Commutators of Cauchy-Szego type integrals for domains in C^n with minimal smoothness

, 2021
In this paper we study the commutator of Cauchy type integrals C on a bounded strongly pseudoconvex domain D in C with boundary bD satisfying the minimum regularity condition C as in the recent result of Lanzani–Stein.

Commutativity and Homotopy-Commutativity [PDF]

, 1964
The aim of this section is to show, by means of the methods developed in Chapter 3, that for an associative H-space G there exist maps G× G → G satisfying certain commutativity conditions (Theorem 4.5). As will be explained in Remarks 4.6 this result is related to the work of other authors on homotopy-commutativity.

On compactness of commutators of multiplication and bilinear pseudodifferential operators and a new subspace of BMO

, 2020
It is known that the compactness of the commutators of point-wise multiplication with bilinear homogeneous Calderon–Zygmund operators acting on product of Lebesgue spaces is characterized by the multiplying function being in the space CMO.
