[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 …

Canonical metrics on holomorphic Courant algebroids

M Garcia‐Fernandez, R Rubio… - Proceedings of the …, 2022 - Wiley Online Library
The solution of the Calabi Conjecture by Yau implies that every Kähler Calabi–Yau manifold
XX admits a metric with holonomy contained in SU (n) SU(n), and that these metrics are …

Heterotic backgrounds via generalised geometry: moment maps and moduli

A Ashmore, C Strickland-Constable… - Journal of High Energy …, 2020 - Springer
A bstract We describe the geometry of generic heterotic backgrounds preserving minimal

Ricci flow on Courant algebroids

J Streets, C Strickland-Constable, F Valach - arXiv preprint arXiv …, 2024 - arxiv.org
We develop a theory of Ricci flow for metrics on Courant algebroids which unifies and
extends the analytic theory of various geometric flows, yielding a general tool for …

The decoupling of moduli about the standard embedding

B Chisamanga, J McOrist, S Picard… - Journal of High Energy …, 2025 - Springer

Special Lagrangian Cycles and Calabi-Yau Transitions

TC Collins, S Gukov, S Picard, ST Yau - Communications in Mathematical …, 2023 - Springer
We construct special Lagrangian 3-spheres in non-Kähler compact threefolds equipped with
