In this talk, we first recall the background of the Calder\'on commutator and connection between the Calder\'on commutator and the Cauchy integral along Lipschits curve, boundary value problems on bounded domains, bilinear Hilbert transforms. Then we give some Calder\'on type commutators, which are the extensions of the Calder\'on commutator. Finally, we present our recent works on Calder\'on type commutators. |
