10.06 Mikołaj Frączyk "Minimal submanifolds of locally symmetric spaces"
Abstract: Minimal submanifolds have been a popular and a useful tool in low dimensional topology, especially in the context of hyperbolic 3-manifolds, providing natural well-behaved representatives of homology or homotopy classes. In more exotic high dimensional hyperbolic manifolds (quaternionic or octonio especially in the context of hyperbolic 3-manifolds, providing natural well-behaved representatives of honic hyperbolic manifolds) a new curious phenomenon takes place. In contrast to the real hyperbolic case, the low codimensional minimal submanifolds are always „big” - they approxiamately occupy positive proportion of the space and their fundamental group surjects onto a finite index subgroup of the fundamental group of the ambient manifold. This result implies that octonionic hyperbolic manifolds are higher expanders in the sense of Gromov and satisfy the power-law systolic freedom. I hope to outline the proof, based on the tension between monotonicity estimates for minimal submanifolds and the bounds on matrix coefficients of unitary representations of rank one Lie groups. Based on a work in progress with Ben Lowe.

Abstract: This is joint work with S. Kołodziej. We develop potential theory for m-subharmonic functions with respect to a Hermitian metric on a Hermitian manifold. First, we show that the complex Hessian operator is well-defined for bounded functions in this class. This allows to define the m-capacity and then showing the quasi-continuity of m-subharmonic functions. Thanks to this we derive other results parallel to those in pluripotential theory such as the equivalence between polar sets and negligible sets. The theory is then used to study the complex Hessian equation on compact Hermitian manifold with boundary, with the right hand side of the equation admitting a bounded subsolution. This is an extension of a recent result of Collins and Picard dealing with classical solutions.

Abstract: In a general L^2 extension theorem of Demailly for log canonical pairs, the L^2 criterion with respect to a measure called the Ohsawa measure determines when a given holomorphic function can be extended. Despite the analytic nature of the Ohsawa measure, we establish a geometric characterization of this analytic criterion using the theory of log canonical centers from algebraic geometry. Along the way, we characterize when the Ohsawa measure fails to have generically smooth positive density, which answers an essential question arising from Demailly's work.

Abstract: Let $\Omega$ be a bounded pseudoconvex domain in $\mathbb C^n$.

16.1 Yuya Takeuchi "CR Paneitz operator and embeddability"
Abstract: Graham and Lee considered the Dirichlet problem on an asymptotically complex hyperbolic space, and defined a differential operator on the boundary as an obstruction to the existence of a solution smooth up to the boundary. This operator, known as the CR Paneitz operator, plays a crucial role in three-dimensional CR geometry; it is deeply connected to global embeddability and the CR positive mass theorem. In this talk, I will show that the CR Paneitz operator is nonnegative for embeddable CR manifolds. The proof is inspired by the Siu-Sampson result for harmonic maps. I will also discuss what happens in the non-embeddable case.

9.1 Seungjae Lee "Weighted Bergman spaces of holomorphic ball bundles"
Abstract: In this talk, we will discuss weighted Bergman spaces of holomorphic ball bundles over compact Kähler manifolds. Since the automorphism group $\mathbb{B}^n$ is canonically embedded into the automorphism group of $\mathbb{P}^n$, any ball bundle is embedded into the associated $\mathbb{P}^n$ bundle as a relatively compact smooth domain. From this viewpoint, it is natural to investigate the Bergman space of these subdomains. In 2017, M. Adachi constructed weighted $L^2$ holomorphic functions on disc-fiber bundles over compact Riemann surfaces. In 2020, A. Seo and S. Lee extended his result to ball-fiber bundles over compact complex hyperbolic space forms using symmetric differentials and a variation of Hodge identities. Moreover, A. Seo and S. Lee recently showed that these phenomena are still valid for some compact submanifolds of finite volume ball quotients. In this talk, we will explain these results and provide some proofs if time permits.

28.11 Bin Guo "Green's functions and complex Monge-Ampère equations"
Abstract: We will discuss a recent joint work with Phong-Sturm on the uniform integral estimates of Green's functions for the Kähler metric. Unlike in the classic theorem of Cheng-Li for Riemannian manifolds, the estimates do not depend directly on the Ricci curvature, but only on integral bounds for the volume form. In particular, a uniform lower bound for the Green's function on Kähler manifolds is obtained which depends only on a lower bound for the scalar curvature and on an L^q norm for the volume form for some q>1.

21.11 Jian Song "Diameter estimates in Kähler geometry"
Abstract: We establish diameter estimates for Kähler metrics, requiring only an entropy bound and no lower bound on the Ricci curvature. As a consequence, diameter bounds are obtained for long-time solutions of the Kähler-Ricci flow and finite-time solutions when the limiting class is big, as well as for special fibrations of Calabi-Yau manifolds.

For notational convenience, I will show the idea by focusing on the complex Hessian equation. This is a joint work with Liding Huang and Jiaogen Zhang.

More recently, quaternionic analogues of them were introduced and studied. In this talk we introduce an analogue of the Calabi problem for two octonionic variables. It is formulated for a special class of 16-dimensional manifolds. The problem is solved under extra assumptions on the manifolds (e.g. for 16-dimensional tori).

In this talk, we prove a generalized version of this theorem, where compact Riemann surfaces are replaced with compact Kähler manifolds. We also discuss its application to the projectivity of manifolds. This is a joint work with Jihun Yum (IBS-CCG).

In his paper, he showed that the geodesic curvature, which measures the positivity of the horizontal direction, satisfies a certain elliptic PDE. Applying the maximum principle to this PDE, he obtained the positivity. In 2013, Berman proved the parabolic version of the Schumacher's result. More precisely, he proved that the geodesic curvature of a family of canonically polarized compact Kähler manifolds satisfies a parabolic equation. A parabolic maximum principle implies that the positivity of the geodesic curvature is preserved along the Kähler-Ricci flow. In this talk, we will briefly introduce the above results and discuss how to apply their methods to several families of Kähler manifolds.

I present a recent joint work with Do Duc Thai in which we characterize the class of probability measures on a compact Kähler manifold such that the associated Monge-Ampère equation has a solution of finite energy. Such a characterization was previously only known in particular cases.

29.11 Zakarias Sjöström Dyrefelt ''Openness of stability in the Kähler cone'' Abstract: With respect to the Yau-Tian-Donaldson (YTD) conjecture a fundamental question is the following: If a polarized manifold is K-stable, then does it remain K-stable under small enough perturbations of the polarization? In this talk we explain why the answer is "yes" when K-stability is replaced by uniform K-stability, thus also strengthening the evidence for the uniform YTD conjecture. During the talk we will discuss in expository terms some of the main difficulties in obtaining such openness results, and finally broadly outline our recent proof. We also point out that the same approach can be applied to show openness of several other stability notions that are commonly studied in Kähler geometry. Even though the problem is phrased in algebro-geometric language, the techniques used to solve it are largely variational. As such we will explain how the result is an application of the theory of energy functionals on the space of Kähler potentials.

19.04 Valentino Tosatti "Higher order estimates for collapsing complex Monge-Ampère equations" Abstract: I will consider a family of complex Monge-Ampère equations on a compact Calabi-Yau manifold which has a fibration structure, with fiber size that is shrinking to zero, whose solutions of these equations give Ricci-flat Kähler metrics on the total space. Each equation is uniquely solvable by classical work of Yau, but understanding their asymptotic behavior as the fiber size shrinks is a very challenging problem. I will discuss very recent work with Hans-Joachim Hein where we prove a priori C^k estimates for all k, away from the singular fibers of the fibration. This is a consequence of an asymptotic expansion for the solution, which relies on a new analytic method where each additional term of the expansion arises as the obstruction to proving a uniform bound on one additional derivative of the remainder.

12.04 Robert Berman "An invitation to Kähler-Einstein metrics and random point processes" Abstract: While the existence of a unique Kähler-Einstein metrics on a canonically polarized manifold X was established already in the seventies there are very few explicit formulas available (even in the case of complex curves!). In this talk I will give a non-technical introduction to a probabilistic approach to Kähler-Einstein metrics, which, in particular, yields canonical approximations of the Kähler-Einstein metric on X. The approximating metrics in question are expressed as explicit period integrals and the conjectural extension to the case of a Fano variety leads to some intriguing connections to zeta functions.

29.03 Vincent Guedj "Finite entropy vs finite energy" Abstract: Probability measures with either finite Monge-Ampère energy or finite entropy have played a central role in recent developments in Kähler geometry. We make a systematic study of quasi-plurisubharmonic potentials whose Monge-Ampère measures have finite entropy. We show that these potentials belong to a critical finite energy class and provide examples showing that the critical exponent is sharp. Our proof relies on refined Moser-Trudinger inequalities for quasi-plurisubharmonic functions. This is joint work with E.Di Nezza and H.C.Lu

We show that if (X_i,g_i) is a sequence in K(n,V), there is a subsequence that converges, in the pointed Gromov-Hausdorff topology, to a finite union of complete Kähler-Einstein metric spaces without loss of volume. Let M(n,V) be the compactified moduli space of all Kähler-Einstein varieties of dimension n and volume at most V. We show that the Weil-Petersson metric, which is a positive closed (1,1) current on the projective variety M(n,V), has continuous local potentials. We also show how one can use these ideas to give a new proof of the Deligne-Mumford stable reduction theorem. This is joint work with Jian Song and Xiaowei Wang.

We characterize rays that can be approximated by ample test configurations. At the same time, we also characterize the closure of algebraic singularity types among all singularity types of quasi-plurisubharmonic functions, pointing out the very close relationship between these two seemingly unrelated problems. By Bonavero's holomorphic Morse inequalities, the arithmetic and non-pluripolar volumes of algebraic singularity types coincide. We show that in general the arithmetic volume dominates the non-pluripolar one, and equality holds exactly on the closure of algebraic singularity types. Joint work with Mingchen Xia.

In the tentative to move from the Kähler to the non-Kähler setting, we consider several problems concerning Hermitian metrics on complex manifolds with special curvature properties that can be translated and attacked as analytic pdes. In this context, we study an analogue of the Yamabe problem for Hermitian manifolds: more precisely, we prove the existence of Hermitian metrics having constant scalar curvature with respect to the Chern connection when the expected curvature is non-positive, and we point out the difficulties in the positive curvature case. This problem relates also to several notions of Chern-Einstein metrics. The plural here refers to the lack of symmetries of the curvature tensor of “canonical” connections of Hermitian manifolds. To the broad subject, the Chern-Ricci flow plays an useful role: the problem of uniform convergence of the normalized Chern-Ricci flow can be dealt with on Inoue-Bombieri surfaces with Gauduchon metrics. The talk is based on joint collaborations with: Simone Calamai, Antonio Otal, Cristiano Spotti, Valentino Tosatti, Luis Ugarte, Raquel Villacampa.

We will present an outline of a current level of knowledge about hypercomplex and HKT manifolds. We will provide some examples of this structures and, finally, we will discuss the construction of so called twistor space associated to any hypercomplex manifold.

It resembles some properties of Monge-Amp\`ere equation and exhibits other special features which are not true for higher dimensional Monge-Amp\`ere equation. The talk will concentrate on two problems: global regularity of immersed hypersurfaces in warped product spaces with nonnegative scalar curvature and interior $C^2$ estimate for immersed hypersurfaces in $R^{n+1}$ with positive scalar curvature (which is not true for $\sigma_k$ curvature equations when $k>2$ by examples of Pogorelov and Urbas). We will explain how special structures of the scalar curvature equation play the role in the estimates and discuss applications to the isometric embedding problem and notion of quasi local masses in general relativity.

The family of threefolds of this degree has many interesting features. In particular, it was extensively studied from the point of view of Tian's alpha-invariants and existence of Kaehler-Einstein metrics. It is known that some of them admit Kaehler-Einstein metrics, while some others do not. In some cases their existence can be deduced from a computation of alpha-invariants. In my talk I will tell about the geometry of Fano threefolds of degree 22 that admit the action of a one-dimensional torus Gm, and about their alpha-invariants. This is a joint work with Ivan Cheltsov.

In this talk, I will quickly summarize the known results to this goal and report my work on the classification of such surfaces. The result is obtained by generalizing the notion of ‘cascades’ of nonsingular del Pezzo surfaces to the singular case. This approach is turned out to be successful when the surface is toric or of Picard number one. At the end of the talk, I will also speak on the Singular Surface Database(SSDB) project which aims to realize this method.

Then, we analyze what happens when we take two K3 surfaces with the same derived category and their hilbert schemes of points. We will show how the birational geometry of IHS manifolds forces these schemes to be non birational in many cases. This is part of a joint work with C. Meachan and K. Yoshioka.

It follows from previous works of Tosatti and Weinkove that the flow carries out blow-downs of exceptional curves on non-minimal surfaces. In this talk I provide more evidence that the Chern-Ricci flow is a natural evolution equation on complex manifolds and that its behavior reflects the underlying geometry.

Abstract: Pseudoconcave CR manifolds attract particular interest since their structural properties resemble (and generalise) aspects known from complex manifolds, and also because of an abundant variety of examples originating from representation theory. In our talk, we discuss work in progress aiming at extending certain aspects of the theory, like the maximum principle and results on envelopes of holomorphy, to general real submanifolds of Cn (where CR dimension may vary with the point). A major part of this is due to joint work with Mauro Nacinovich (Rome 2).
