The aim of this book is to provide a self-contained introduction and an up-to-date survey on many aspects of the theory of transport equations and ordinarydifferential equations with non-smooth velocity fields. The interest in this topic is motivated by important issues in nonlinear PDEs, in particular conservation laws and fluid mechanics. A fascinating feature of this research area, which is currently of concern in mathematics, is the interplay between PDE techniques and geometric measure theory techniques. Several masterpieces appear in the related literature, balancing completely rigorous proofs with more heuristic arguments. A consistent part of the book is based on results obtained by the author in collaboration with other mathematicians. After a short introduction to the classical smooth theory, the book is divided into two parts. The first part focuses on the PDE aspect of the problem, presenting some general tools of this analysis, many well-posedness results, an abstract characterizationof the well-posedness, and some examples showing the sharpness of the assumptions made. The second part, instead, deals with the ODE aspect of the problem,respectively by an abstract connection with the PDE, and by some direct and simple (but powerful) a priori estimates. Self-contained introduction and an upto date survey on many aspects of the theory of transport equations and ordinary differential equations with non-smooth velocity fields Presentation of theliterature on this topic by balancing heuristic motivations with rigorous proofs Two parts: the first one devoted to the PDE analysis, and the second one to ODE theory, relying both on the connection with the PDE and on some direct estimates
