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.
