A gluing construction of -extremal Kähler metrics and new examples of Bismut Hermitian-Einstein -folds

Vestislav Apostolov, Abdellah Lahdili, Kuan-Hui Lee +1

We present a gluing construction for a class of 6th order geometric non-linear PDE's on a Kähler manifold or orbifold, arising in the study of Bismut Hermitian Einstein complex …

Pluriclosed 3-folds with vanishing Bismut Ricci form: General theory in the quasi-regular case

Vestislav Apostolov, Abdellah Lahdili, Kuan-Hui Lee

We study compact complex -dimensional non-Kähler Bismut Ricci flat pluriclosed Hermitian manifolds (BHE) via their dimensional reduction to a special Kähler geometry in complex…

The CR Yamabe invariant and constant scalar curvature Sasaki metrics

Abdellah Lahdili, Eveline Legendre, Carlo Scarpa

We propose a new approach to the existence of constant transversal scalar curvature Sasaki structures drawing on ideas and tools from the CR Yamabe problem, establishing a link bet…

The weighted Hermite--Einstein equation

Michael Hallam, Abdellah Lahdili

We introduce a new weighted version of the Hermite--Einstein equation, along with notions of weighted slope (semi/poly)stability, and prove that a vector bundle admits a weighted H…

Mabuchi Kähler solitons versus extremal Kähler metrics and beyond

Vestislav Apostolov, Abdellah Lahdili, Yasufumi Nitta

Using the Yau-Tian-Donaldson type correspondence for -solitons established by Han-Li, we show that a smooth complex -dimensional Fano variety admits a Mabuchi soliton provide…

The Einstein-Hilbert functional and the Donaldson-Futaki invariant

Abdellah Lahdili, Eveline Legendre, Carlo Scarpa

Given a Kaehler manifold polarised by a holomorphic ample line bundle, we consider the circle bundle associated to the polarisation with the induced transversal holomorphic structu…
