On the canonical line bundle and negative holomorphic sectional curvature
We prove that a smooth complex projective threefold with a Kähler metric of negative holomorphic sectional curvature has ample canonical line bundle.In dimensions greater than three, we prove that, under equal assumptions, the nef dimension of the canonical line bundle is maximal.With certain additional assumptions, ampleness is again obtained.The methods …
