Geometric interpretation of the vanishing Lie Bracket for two-dimensional rough vector fields

Analysis of PDEs 2025-03-12 v2

Abstract

In this paper, we prove that if X,YX,Y are continuous, Sobolev vector fields with bounded divergence on the real plane and [X,Y]=0[X,Y]=0, then their flows commute. In particular, we improve the previous result of Colombo-Tione (2021), where the authors require the additional assumption of the weak Lie differentiability on one of the two flows. We also discuss possible extensions to the BV\text{BV} setting.
