on W consider the space of finite divergence free B vector measures, Bonicatto. endowed with the total variation norm. F we present a characterization of the extreme points of the unit ball in this space. T allows one to decompose (for ) any finite divergence free vector measure into measures induced by closed L curves. T results are based on a joint work with P. On the Extreme Points of the Unit Ball in the Space of Solenoidal Vector Measures on the Plane. DNC. 2026;9(4):525-528. doi:10.5890/DNC.2020.12.005
