Integrating holomorphic sectional curvatures
Gunnar Þór Magnússon
We calculate the -norm of the holomorphic sectional curvature of a Kähler metric by representation-theoretic means. This yields a new proof that the holomorphic sectional curv…
On the curvature of the blowup of a point
Gunnar Þór Magnússon
We consider the blowup of a point of a compact Kähler manifold and a metric of the form on it, where is a Kähler metric on the original manifold and is Hermiti…
A remark on Wu's remark on holomorphic sectional curvature
Gunnar Þór Magnússon
We give a quick direct proof of Wu's theorem on the subadditivity of Hermitian metrics of negative holomorphic sectional curvature.
Degenerate Hermitian geometry and curvatures of holomorphic fibrations
Gunnar Þór Magnússon
We calculate curvature tensors of metrics on the total spaces of holomorphic fibrations. Our main tool is a theory of Chern connections and curvature forms for possibly degenerate…
Cohomological expression of the curvature of Kähler moduli
Gunnar Þór Magnússon
The Kähler cone of a compact Kähler manifold carries a natural Riemannian metric, given by the intersection product of its cohomology ring. We give cohomological expressions for th…
