In DL89, R.J. DiPerna and P.-L. Lions first proved that Sobolev regularity for vector fields in $\mathbb{R}^n$ (with bounded divergence) is sufficient to establish existence, uniqueness and stability of a generalized notion of flow, consisting of a suitable selection among the trajectories of the associated ODE: later on, the important case of BV fields was settled by L. Ambrosio, in Amb04.

In this seminar we will introduce and motivate the infinite dimensional counterparts of these results, in the setting of abstract Wiener spaces, as developed in AF09 (Sobolev fields) and in Tre13 (BV fields).
