Conformally Einstein Products and Nearly Kähler Manifolds
International audienceIn the first part of this note we study compact Riemannian manifolds (M,g) whose Riemannian product with R is conformally Einstein.

Vanishing theorems on compact Chern-Kähler-like Hermitian manifolds
We show that, under the definiteness of holomorphic sectional curvature, the spaces of some holomorphic tensor fields on compact Chern-Kähler-like Hermitian manifolds are trivial.

We analyze degenerate homogeneous structures of linear type in the pseudo-Kähler and para-Kähler cases. The local form and the holonomy of pseudo-K¨ahler or para-K¨ahler manifolds admitting such structure are obtained.

Type I Almost-Homogeneous Manifolds of Cohomogeneity One—IV
This paper is one of a series in which we generalize our earlier results on the equivalence of existence of Calabi extremal metrics to the geodesic stability for any type I compact complex almost homogeneous manifolds of cohomogeneity one. In this paper,

Minimal two spheres in Kähler–Einstein Fano manifolds
In this paper we show the existence of stable symplectic non-holomorphic two-spheres in Kähler manifolds of positive constant scalar curvature of real dimension four and in Kähler–Einstein Fano manifolds of real dimension six. Some of the techniques used

Fibred GK geometry and supersymmetric AdS solutions
We continue our study of a general class of N = 2 $$ \mathcal{N}=2 $$ supersymmetric AdS3 × Y7 and AdS2 × Y9 solutions of type IIB and D = 11 supergravity, respectively.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Cohomology of D-complex manifolds
In order to look for a well-behaved counterpart to Dolbeault cohomology in D-complex geometry, we study the de Rham cohomology of an almost D-complex manifold and its subgroups made up of the classes admitting invariant, respectively anti-invariant ...

Balanced Metrics and Noncommutative Kähler Geometry
In this paper we show how Einstein metrics are naturally described using the quantization of the algebra of functions C^∞(M) on a Kähler manifold M. In this setup one interprets M as the phase space itself, equipped with the Poisson brackets inherited ...
