Abstract
We construct a large class of incompressible vector fields with Sobolev regularity, in dimension , for which the chain rule problem has a negative answer. In particular, for any renormalization map (satisfying suitable assumptions) and any (distributional) renormalization defect of the form , where is an vector field, we can construct an incompressible Sobolev vector field and a density for which but , provided
