摘 要： In this talk, we discuss the positivity of complete intersections of nef classes, including sufficient and necessary characterizations of the hard Lefschetz property on a compact complex torus and the non-vanishing property on an arbitrary compact Kahler manifold. We also discuss some combinatorial aspects (polymatroid structures) closely related to these results. Joint work with J. Hu.
