摘要：First, we introduce the background of k-Ricci curvature. Then we discuss some important results on Kahler manifolds with non-negative or non-positive k-Ricci curvature. Finally, we consider a natural notion of “almost nonpositive k-Ricci curvature”, which is weaker than the existence of a Kahler metric with nonpositive k-Ricci curvature. We prove that a compact Kahler manifold of almost non-positive k-Ricci curvature must have nef canonical line bundle.
