Abstract

We provide a natural BMO-criterion for the L2L_2-boundedness of Calder\'on-Zygmund operators with operator-valued kernels satisfying a symmetric property. Our arguments involve both classical and quantum probability theory. In the appendix, we give a proof of the L2L_2-boundedness of the commutators [Rj,b][R_j,b] whenever bb belongs to the Bourgain's vector-valued BMO space, where RjR_j is the jj-th Riesz transform. A common ingredient is the operator-valued Haar multiplier studied by Blasco and Pott.
