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 thi…

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…

The Riemannian and symplectic geometry of the space of generalized Kähler structures

Vestislav Apostolov, Jeffrey Streets, Yury Ustinovskiy

On a compact complex manifold endowed with a holomorphic Poisson tensor and a deRham class , we study the space of generalized Kähler (GK) st…

The generalized Kähler Calabi-Yau problem

Vestislav Apostolov, Xin Fu, Jeffrey Streets +1

We formulate an extension of the Calabi conjecture to the setting of generalized Kähler geometry. We show a transgression formula for the Bismut Ricci curvature in this setting, wh…

On geometry of steady toric Kähler-Ricci solitons

Yury Ustinovskiy

In this paper we study the gradient steady Kähler-Ricci soliton metrics on non-compact toric manifolds. We show that the orbit space of the free locus of such a manifold carries a…

Variational structure and uniqueness of generalized Kähler-Ricci solitons

Vestislav Apostolov, Jeffrey Streets, Yury Ustinovskiy

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 classic…

Generalized Kähler-Ricci flow on toric Fano varieties

Vestislav Apostolov, Jeffrey Streets, Yury Ustinovskiy

We study the generalized Kähler-Ricci flow with initial data of symplectic type, and show that this condition is preserved. In the case of a Fano background with toric symmetry, we…

The Gibbons-Hawking ansatz in generalized Kähler geometry

Jeffrey Streets, Yury Ustinovskiy

We derive a local ansatz for generalized Kähler surfaces with nondegenerate Poisson structure and a biholomorphic action which generalizes the classic Gibbons-Hawking ansatz…

Classification of generalized Kähler-Ricci solitons on complex surfaces

Jeffrey Streets, Yury Ustinovskiy

Using toric geometry we give an explicit construction of the compact steady solitons for pluriclosed flow first constructed in arXiv:1802.00170. This construction also reveals that…

On the Structure of Hermitian Manifolds with Semipositive Griffiths Curvature

Yury Ustinovskiy

In this paper we establish partial structure results on the geometry of compact Hermitian manifolds of semipositive Griffiths curvature. We show that after appropriate arbitrary sm…

Hermitian curvature flow on complex homogeneous manifolds

Yury Ustinovskiy

In this paper we study a version of the Hermitian curvature flow (HCF). We focus on complex homogeneous manifolds equipped with induced metrics. We prove that this finite-dimension…
