Title: On commutators of singular integral operators with BMO functions

Speaker: Carlos Perez (University of Basque Country)

Date: 28 March 2017

Time: 4pm

Venue: LH-1, Mathematics Department

Commutators of singular integral operators with BMO functions were introduced in the seventies by Coifman-Rochberg and Weiss. These operators are very interesting for many reasons, one of them being the fact that they are more singular than Calderon-Zygmundm operators. In this lecture we plan to give several reasons showing the ``bad” behavior of these operators.
