摘要：

We completely classify three-dimensional semi-symmetric Lorentzian manifolds which are curvature homogeneous up to order one. Curvature restrictions for semi-symmetry turn out to be the same ones which ensure the existence on these manifolds of a degenerate parallel null line field (Chaichi et al., J. Phys. A, Math. Gen. 38, 841-850, 2005).
