GAIA Seminar on complex Analytic Geometry_Dr. Ngoc Cuong Nguyen

- Title: Holder continuous solutions of the Monge-Ampere equation on compact Hermitian manifolds 

- Speaker: Dr. Ngoc Cuong Nguyen (GAIA)

 

- Abstract: 

This is a joint work with S. Kolodziej. We show that a positive Borel measure of finite total mass, on compact Hermitian manifolds, admits a Holder continuous quasi-plurisubharmonic solution to the Monge-Ampere equation if and only if it is dominated locally by Monge-Ampere measures of Holder continuous plurisubharmonic functions.

- Title: Compactness of certain families of pseudo-holomorphic mapping into Cn

 

- Speaker: Dr. Seungro Joo (POSTECH)

 

- Abstract: 

We study a concept of the convexity index, which is define in[I].

In this paper, Gaussier & Kim showed some normal family arguments for the sequence whose image has a uniform positive lower bound of the convexity index.

GAIA Seminar on Complex Analytic Geometry - Sachiko Hamano

- Title:  Variation of the moduli disk for an open Riemann surface of finite genus

- Speaker: Prof. Sachiko Hamano (Osaka City University, Japan)

- Abstract:

For an open Riemann surface R of finite genus, we shall consider conformal embeddings of R into closed ones of the same genus. The closing induces the Riemann's period matrix T. Masakazu Shiba and Hiroshi Yamaguchi recently showed that each diagonal element of T describes a close disk M in the upper half plane.

 In this talk, we shall consider the deforming open Riemann surface R(t) of finite genus with complex parameter t, and show the close relation between pseudoconvexity and the closed disk M(t) for R(t).

 This talk is based on a joint work with H.Yamaguchi.

- Title:  Estimates of squeezing function of Thullen domain at the origin

- Speaker: Sejun Kim (POSTECH Graduate student)

- Abstract: In the paper of Deng-Guan-Zhang, they showed that there exists one-to-one function from bounded domain to unit ball which realizes squeezing function value. But for arbitrary bounded domain, founding the squeezing function value and the realizing function is very hard. In this talk, I will talk how to estimate of squeezing function of Thullen domain at the origin.

-  Title: A Kobayashi pseudo-distance for holomorphic bracket generating distributions

-  Speaker: Dr. Ae-Ryeong Seo (KIAS)

- Abstract: In this talk, I will generalize the Kobayashi pseudo-distance to complex manifolds which admit holomorphic bracket generating distributions. The generalization is based on Chow's theorem in sub-Riemannian geometry. For a complex homogeneous manifold with an invariant holomorphic bracket generating distribution, the universal covering of $M$ is a canonical flag domain under certain condition.
