Some problems in analysis benefit from an understanding of the commutation between certain operators or the factori zation of functions from natural function spaces. These topics all intera ct when studying the commutators of Calder\\'on-Zygmund operators and mult iplication operators. In this talk\, we will discuss some recent results about commutators of certain Calderon-Zygmund operators and BMO spaces and how these generate bounded operators on Lebesgue spaces. Motivations and connections to operator theory and partial differential equations will be provided. Versions of these results on the Heisenberg group\, pseudoconv ex domains with $C^2$ boundary\, and other examples will be explained to s how how the general theory carries over to many other settings. This talk is based on joint collaborative work.\n LOCATION:https://researchseminars.org/talk/ags/16/ END:VEVENT END:VCALENDAR
