Abstract
In this paper we extend the bump conjecture and a particular case of the separated bump conjecture with logarithmic bumps to iterated commutators Tbm. Our results are new even for the first order commutator Tb1. A new bump type necessary condition for the two-weighted boundedness of Tbm is obtained as well. We also provide some results related to a converse to Bloom's theorem.
