Existence of a complete holomorphic vector field via the Kähler-Einstein metric

Young-Jun Choi, Kang-Hyurk Lee

In this paper, we study the existence of a complete holomorphic vector fields on a strongly pseudoconvex complex manifold admitting a negatively curved complete Kähler-Einstein met…

Linear series on a curve of compact type bridged by a chain of elliptic curves

Youngook Choi, Seonja Kim

In the present paper we investigate conditions for the non-existence of a limit linear series on a curve of compact type such that two smooth curves are bridged by a chain of two e…

Semi-continuity of the Diederich-Fornaess and Steinness indices

Young-Jun Choi, Jihun Yum

In this paper, we prove the semi-continuity theorem of Diederich-Fornæss index and Steinness index under a smooth deformation of pseudoconvex domains in Stein manifolds.

Holomorphic family of strongly pseudoconvex domains in a Kähler manifold

Young-Jun Choi, Sungmin Yoo

Let be a surjective holomorphic mapping between Kähler manifolds. Let be a bounded smooth domain in such that every generic fiber
