Abstract

We prove quantitative estimates on flows of ordinary differential equations with vector field with gradient given by a singular integral of an L1L^1 function. Such estimates allow to prove existence, uniqueness, quantitative stability and compactness for the flow, going beyond the BVBV theory. We illustrate the related well-posedness theory of Lagrangian solutions to the continuity and transport equations.
