Query: Quadratic $A_1$ bounds for commutators of singular integrals with BMO
  functions   For commutators of the form [b,T] where T is any Calderon--Zygmund operator
and b is any BMO function we derive weighted quadratic type estimates in term
of the A1 constant of the weight both in the Lp context or of LlogL type at the
endpoint
