## Algebraicity of the metric tangent cones Wang, Xiaowei | CIRM H

Post-edited

Research talks;Algebraic and Complex Geometry

We proved that any K-semistable log Fano cone admits a special degeneration to a uniquely determined K-polystable log Fano cone. This confirms a conjecture of Donaldson-Sun stating that the metric tangent cone of any close point appearing on a Gromov-Hausdorff limit of Kähler-Einstein Fano manifolds depends only on the algebraic structure of the singularity. This is a joint work with Chi Li and Chenyang Xu.

## Moduli of algebraic varieties Dervan, Ruadhai | CIRM H

Multi angle

Research talks;Algebraic and Complex Geometry

One of the central problems in algebraic geometry is to form a reasonable (e.g. Hausdorff) moduli space of smooth polarised varieties. I will show how one can solve this problem using canonical Kähler metrics. This is joint work with Philipp Naumann.

## Apriori estimates for scalar curvature type equations on compact Kähler manifolds Cheng, Jingrui | CIRM H

Multi angle

Research talks;Partial Differential Equations;Algebraic and Complex Geometry

We develop apriori estimates for scalar curvature type equations on compact Kähler manifolds. As an application, we show that K-energy being proper with respect to $L^1$ geodesic distance implies the existence of constant scalar curvature Kähler metrics. This is joint work with Xiuxiong Chen.

## Pluripotential Kähler-Ricci flows Guedj, Vincent | CIRM H

Multi angle

Research talks;Analysis and its Applications;Partial Differential Equations;Algebraic and Complex Geometry

We develop a parabolic pluripotential theory on compact Kähler manifolds, defining and studying weak solutions to degenerate parabolic complex Monge-Ampere equations. We provide a parabolic analogue of the celebrated Bedford-Taylor theory and apply it to the study of the Kähler-Ricci flow on varieties with log terminal singularities.

## Complex Monge-Ampere equations with prescribed singularities​ Di Nezza, Eleonora | CIRM H

Multi angle

Research talks;Analysis and its Applications;Partial Differential Equations;Algebraic and Complex Geometry

Since the proof of the Calabi conjecture given by Yau, complex Monge-Ampère equations on compact Kähler manifolds have been intensively studied.
In this talk we consider complex Monge-Ampère equations with prescribed singularities. More precisely, we fix a potential and we show existence and uniqueness of solutions of complex Monge-Ampère equations which have the same singularity type of the model potential we chose. This result can be interpreted as a generalisation of Yau’s theorem (in this case the model potential is smooth).
As a corollary we obtain the existence of singular Kähler-Einstein metrics with prescribed singularities on general type and Calabi-Yau manifolds.
This is a joint work with Tamas Darvas and Chinh Lu.

## Kodaira dimension of algebraic fiber spaces over abelian varieties or projective surfaces Cao, Junyan | CIRM H

Multi angle

Research talks;Algebraic and Complex Geometry

Let $f : X \to Y$ be a fibration between two projective manifolds. The Iitaka’s conjecture predicts that the Kodaira dimension of $X$ is larger than the sum of the Kodaira dimension of $X$ and the Kodaira dimension of the generic fiber. We explain a proof of the Iitaka conjecture for algebraic fiber spaces over abelian varieties or projective surfaces.
It is a joint work with Mihai Paun.
