Hermitian Calabi functional in complexified orbits

J He, K Zheng - arXiv preprint arXiv:2303.00631, 2023 - arxiv.org
Let $(M,\omega) $ be a compact symplectic manifold. We denote by $\ac $ the space of all
almost complex structure compatible with $\omega $. $\ac $ has a natural foliation structure …

We study the problem of existence of K\" ahler--Einstein metrics on smooth Fano threefolds
of Picard rank one and anticanonical degree $22 $ that admit a faithful action of the …

Stability under deformations of Hermite-Einstein almost Kähler metrics

M Lejmi - Annales de l'Institut Fourier, 2014 - numdam.org
On a 4-dimensional compact symplectic manifold, we consider a smooth family of
compatible almost-complex structures such that at time zero the induced metric is Hermite …

Remarks on Mukai threefolds admitting action

S Dinew, G Kapustka, M Kapustka - arXiv preprint arXiv:1506.03286, 2015 - arxiv.org
We investigate geometric invariants of the one parameter family of Mukai threefolds that
admit $\mathbb C^{*} $ action. In particular we find the invariant divisors in the anticanonical …

Stability of Sasaki-extremal metrics under complex deformations

C van Coevering - International Mathematics Research Notices, 2013 - ieeexplore.ieee.org
We consider the stability of Sasaki-extremal metrics under deformations of the transversal
complex structure of the foliation \mathscrF_ξ induced by the Reeb vector field ξ. Let g be a …

On deformations of Fano manifolds

HD Cao, X Sun, ST Yau, Y Zhang - Mathematische Annalen, 2022 - Springer
In this paper, we provide new necessary and sufficient conditions for the existence of Kähler–
Einstein metrics on small deformations of a Fano Kähler–Einstein manifold. We also show …

Deformations of Fano manifolds with weighted solitons

A Futaki - arXiv preprint arXiv:2305.03544, 2023 - arxiv.org
We consider weighted solitons on Fano manifolds which include Kaehler-Ricci solitons,
Mabuchi solitons and base metrics which induce Calabi-Yau cone metrics outside the zero …

Deformation for coupled Kähler–Einstein metrics

S Nakamura - Journal of the Mathematical Society of Japan, 2021 - jstage.jst.go.jp
The notion of coupled Kähler–Einstein metrics was introduced recently by Hultgren–Witt
Nyström. In this paper we discuss deformation of a coupled Kähler–Einstein metric on a …
