Webb23 okt. 2016 · When the metric is Kähler, this is just the holomorphic sectional curvature , and when the metric is non-Kähler, it is slightly stronger than . We classify compact Hermitian manifolds with constant non-zero real bisectional curvature, and also slightly extend Wu-Yau's theorem to the Hermitian case. WebbA Kähler Manifold is an hermitian manifold, whose Kälher form is closed i.e. d Ω = 0. A Hermitian manifold is a complex manifold equipped with a metric g , such that g p ( X, Y) = g p ( J p X, J p Y), where p ∈ M and X, Y ∈ T p M.

Webb29 apr. 2024 · Here, ˆω is a kähler form whose holomorphic sectional curvature is (strictly/semi-) negative. The objective of this note is to simplify the proofs by replacing ωε by the Kähler-Ricci flow ωt⁠. These theorems are originated from the conjecture of Yau (see [ 4, Conjecture 1.2]). WebbWe then prove that if a Calabi-Yau manifold is sufficiently volume collapsed with bounded diameter and sectional curvature, then it admits a Ricci-flat Kähler metrictogether with a compatible pure nilpotent Killing structure: this is related to an open question of Cheeger, Fukaya and Gromov.
