Poisson K-stability and the semiclassical Yau--Tian--Donaldson correspondence

Vestislav Apostolov, Brent Pym, Jeffrey Streets

We introduce a notion of K-polystability for compact Kähler holomorphic Poisson manifolds. On the one hand, this notion of stability is well-adapted to constructions of moduli spa…

From Calabi's extremal metrics to scalar-flat Kähler cones

Vestislav Apostolov, Abdellah Lahdili, Chung-Ming Pan

We prove that for any smooth polarized complex -dimensional manifold which admits an extremal Kähler metric in , and for any integer large enough (in t…

Formal structure of scalar curvature in generalized Kähler geometry

Vestislav Apostolov, Jeffrey Streets, Yury Ustinovskiy

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 Courant alg…

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 comple…

Rigidity results for non-Kähler Calabi-Yau geometries on threefolds

Vestislav Apostolov, Giuseppe Barbaro, Kuan-Hui Lee +1

We derive a canonical symmetry reduction associated to a compact non-Kähler Bismut-Hermitian-Einstein manifold. In real dimension , the transverse geometry is conformally Kähl…

Toric geometry of generalized Kähler-Ricci solitons

Vestislav Apostolov, Giuseppe Barbaro, Jeffrey Streets +1

We establish a local equivalence between toric steady Kähler-Ricci solitons and -type toric generalized Kähler-Ricci solitons (GKRS). Under natural global conditions we show t…
