Let(X,Δ)be a4-dimensional log variety which is proper over the field of complex numbers and with only divisorial log terminal singularities. The log canonical divisorKX+Δis semiample, if it is numerically effective (NEF) and the Iitaka dimensionκ(X,KX+Δ)is strictly positive. For the proof, we use Fujino's abundance theorem for semi-log canonical threefolds.
