Mass in Kähler geometry

HJ Hein, C LeBrun - Communications in Mathematical Physics, 2016 - Springer
We prove a simple, explicit formula for the mass of any asymptotically locally Euclidean
(ALE) Kähler manifold, assuming only the sort of weak fall-off conditions required for the …

A smörgåsbord of scalar-flat Kähler ALE surfaces

MT Lock, JA Viaclovsky - Journal für die reine und angewandte …, 2019 - degruyter.com
There are many known examples of scalar-flat Kähler ALE surfaces, all of which have group
at infinity either cyclic or contained in SU⁢(2). The main result in this paper shows that for …

Deformation theory of scalar-flat Kähler ALE surfaces

J Han, JA Viaclovsky - American Journal of Mathematics, 2019 - muse.jhu.edu
We prove a Kuranishi-type theorem for deformations of complex structures on ALE K\" ahler
surfaces. This is used to prove that for any scalar-flat K\" ahler ALE surface, all small …

On the Kummer construction for Kcsc metrics

C Arezzo, AD Vedova, R Lena, L Mazzieri - Bollettino dell'Unione …, 2019 - Springer
Given a compact constant scalar curvature Kähler orbifold, with nontrivial holomorphic
vector fields, whose singularities admit a local ALE Kähler Ricci-flat resolution, we find …

Existence and compactness theory for ALE scalar-flat Kähler surfaces

J Han, JA Viaclovsky - Forum of Mathematics, Sigma, 2020 - cambridge.org
Our main result in this article is a compactness result which states that a noncollapsed
sequence of asymptotically locally Euclidean (ALE) scalar-flat Kähler metrics on a minimal …

K-stability, Futaki invariants and cscK metrics on orbifold resolutions

C Arezzo, A Della Vedova, L Mazzieri - arXiv preprint arXiv:1808.08420, 2018 - arxiv.org
In this paper we compute the Futaki invariant of adiabatic Kaehler classes on resolutions of
Kaehler orbifolds with isolated singularities. Combined with previous existence results of …

Expansions of solutions to extremal metric type equations on blowups of cscK surfaces

VV Datar - Annals of Global Analysis and Geometry, 2019 - Springer
The aim of this article is to study expansions of solutions to an extremal metric type equation
on the blowup of constant scalar curvature Kähler surfaces. This is related to finding …

Big and nef classes, Futaki Invariant and resolutions of cubic threefolds

C Arezzo, AD Vedova - Geometric Analysis: In Honor of Gang Tian's 60th …, 2020 - Springer
In this note we revisit and extend few classical and recent results on the definition and use of
the Futaki invariant in connection with the existence problem for Kähler constant scalar …
