Abstract: Log-symplectic manifolds are manifolds with a symplectic form that has logarithmic singularities. In this talk we give a classification of log-symplectic 4-manifolds which admit a ruling, i.e. a symplectic fibration with fiber the complex projective line. The proof is based on the study of moduli spaces of holomorphic curves
