[HTML][HTML] Non-Kähler Calabi-Yau geometry and pluriclosed flow

M Garcia-Fernandez, J Jordan, J Streets - Journal de Mathématiques Pures …, 2023 - Elsevier
Hermitian, pluriclosed metrics with vanishing Bismut-Ricci form give a natural extension of
Calabi-Yau metrics to the setting of complex, non-Kähler manifolds, and arise independently …

Gauge theory for string algebroids

M Garcia-Fernandez, R Rubio… - Journal of Differential …, 2024 - projecteuclid.org
We introduce a moment map picture for holomorphic string algebroids where the
Hamiltonian gauge action is described by means of inner automorphisms of Courant …

Generalized Ricci Flow

M Garcia-Fernandez, J Streets - arXiv preprint arXiv:2008.07004, 2020 - arxiv.org
This book gives an introduction to fundamental aspects of generalized Riemannian,
complex, and K\" ahler geometry. This leads to an extension of the classical Einstein-Hilbert …

Brane quantization of toric Poisson varieties

F Bischoff, M Gualtieri - Communications in Mathematical Physics, 2022 - Springer
In this paper we propose a noncommutative generalization of the relationship between
compact Kähler manifolds and complex projective algebraic varieties. Beginning with a …

The Generalised Complex Geometry of (pq) Hermitian Geometries

C Hull, U Lindström - Communications in Mathematical Physics, 2020 - Springer
We define (p, q) Hermitian geometry as the target space geometry of the two dimensional (p,
q) supersymmetric sigma model. This includes generalised Kähler geometry for (2, 2) …

The generalized K\" ahler Calabi-Yau problem

V Apostolov, X Fu, J Streets, Y Ustinovskiy - arXiv preprint arXiv …, 2022 - arxiv.org
We formulate an extension of the Calabi conjecture to the setting of generalized K\" ahler
geometry. We show a transgression formula for the Bismut Ricci curvature in this setting …

Variational structure and uniqueness of generalized Kähler–Ricci solitons

V Apostolov, J Streets, Y Ustinovskiy - Peking Mathematical Journal, 2023 - Springer
Under broad hypotheses we derive a scalar reduction of the generalized Kähler–Ricci
soliton system. We realize solutions as critical points of a functional, analogous to the …

The Riemannian and symplectic geometry of the space of generalized K\" ahler structures

V Apostolov, J Streets, Y Ustinovskiy - arXiv preprint arXiv:2302.07314, 2023 - arxiv.org
On a compact complex manifold $(M, J) $ endowed with a holomorphic Poisson tensor
$\pi_J $ and a deRham class $\alpha\in H^ 2 (M,\mathbb R) $, we study the space of …

Formal structure of scalar curvature in generalized K\" ahler geometry

V Apostolov, J Streets, Y Ustinovskiy - arXiv preprint arXiv:2404.14595, 2024 - arxiv.org
Building on works of Boulanger and Goto, we show that Goto's scalar curvature is the
moment map for an action of generalized Hamiltonian automorphisms of the associated …

Lie Theory in Generalized Kähler Geometry

Y Jiang - 2023 - search.proquest.com
Generalized Kähler (GK) geometry was discovered in the study of N=(2, 2) supersymmetric σ-
models. In this thesis we develop a new approach to GK geometry by addressing the …
