Kähler–Einstein metrics with prescribed singularities on Fano manifolds [PDF]
Given a Fano manifold ( X , ω ) {(X,\omega)} , we develop a variational approach to characterize analytically the existence of Kähler–Einstein metrics with prescribed singularities, assuming that these singularities can be approximated algebraically ...

Continuity of delta invariants and twisted K\"ahler--Einstein metrics. [PDF]
We show that delta invariant is a continuous function on the big cone. We will also introduce an analytic delta invariant and show its continuity in the Kahler cone, from which we deduce the continuity of the greatest Ricci lower bound.

Geometry of Twisted Kähler–Einstein Metrics and Collapsing [PDF]
We prove that the twisted Kähler–Einstein metrics that arise on the base of certain holomorphic fiber space with Calabi–Yau fibers have conical-type singularities along the discriminant locus.

Canonical metrics on generalized Hartogs triangles
This paper is concerned with the canonical metrics on generalized Hartogs triangles. As main contributions, we first show the existence of a Kähler–Einstein metric on generalized Hartogs triangles.

Quot-scheme limit of Fubini-Study metrics and Donaldson's functional for vector bundles [PDF]
For a holomorphic vector bundle $E$ over a polarised K\"ahler manifold, we establish a direct link between the slope stability of $E$ and the asymptotic behaviour of Donaldson's functional, by defining the Quot-scheme limit of Fubini-Study metrics.

Homogeneous Einstein metrics and butterflies
M.~M.~Graev associated in \cite{Gr} to a compact homogeneous space $G/H$ a nerve $\XGH$, whose non-contractibility implies the existence of a $G$-invariant Einstein metric on $G/H$. The nerve $\XGH$ is a compact semi-algebraic set, defined purely Lie theoretically by intermediate subgroups. In this paper we present a detailed description of the work of

Stability of Einstein metrics on homogeneous spaces [PDF]
(1) Stability of Einstein metrics on symmetric spaces of compact type: We prove the linear stability with respect to the Einstein-Hilbert action of the symmetric spaces SU(n), n ≥ 3, and E_6/F_4 .

Kähler–Einstein metrics on orbifolds and Einstein metrics on spheres
A construction of Kähler–Einstein metrics using Galois coverings, studied by Arezzo–Ghigi–Pirola, is generalized to orbifolds. By applying it to certain orbifold covers of ℂℙ^n which are trivial set theoretically, one obtains new Einstein metrics on
