摘要：
R. Caddeo et al. introduced the notion of bi-conservative submanifolds. By definition, such submanifolds have free divergence bi-tensor field, i.e. div S-2 = 0, which is a generalization of biharmonic submanifolds. This work is done by proving that bi-conservative surfaces in the 3-dimensional Minkowski space are locally CMC surfaces, revolution of surfaces or null scrolls. (C) 2013 Elsevier B.V.
