Kähler–Einstein metrics on group compactifications

Geometric and Functional Analysis, 2015
We obtain a necessary and sufficient condition of existence of a Kähler–Einstein metric on a G × G-equivariant Fano compactification of a complex connected reductive group G in terms of the associated polytope.

Einstein metrics, harmonic forms, and symplectic four-manifolds

, 2014
If $$M$$M is the underlying smooth oriented four-manifold of a Del Pezzo surface, we consider the set of Riemannian metrics $$h$$h on $$M$$M such that $$W^+(\omega , \omega )> 0$$W+(ω,ω)>0, where $$W^+$$W+ is the self-dual Weyl curvature of $$h$$h, and $$

Existence of weak conical Kähler–Einstein metrics along smooth hypersurfaces

, 2013
The existence of weak conical Kähler–Einstein metrics along smooth hypersurfaces with cone angle between $$0$$0 and $$2\pi $$2π is obtained by studying a family of Aubin’s (J Funct Anal 57:143–153, 1984) continuity paths and obtaining a uniform $$C^2$$C2

Desingularisation of Einstein metrics. I

2013
The author studies a new obstruction for a real Einstein 4-orbifold \((M_0,g_0)\) with \(A_1\)-singularity to be a limit of smooth Einstein 4-manifolds. The author proves that if \((M_0,g_0)\) with a nondegenerate asymptotically hyperbolic metric \(g_0\) has a singularity of the type \(\mathbb R^4\slash \mathbb Z_2\) at a point \(p_0\) and \(M\) is a ...

Homogeneous Einstein and Einstein–Randers metrics on Stiefel manifolds

Mathematische Nachrichten
AbstractWe study invariant Einstein metrics and Einstein–Randers metrics on the Stiefel manifold . We use a characterization for (nonflat) homogeneous Einstein–Randers metrics as pairs of (nonflat) homogeneous Einstein metrics and invariant Killing vector fields.
