Kähler Hyperbolicity Modulus for Simply-connected Kähler Hyperbolic manifolds

Young-Jun Choi, Kang-Hyurk Lee

This paper investigates the Kähler hyperbolicity modulus on complete Kähler manifolds, with a particular focus on hyperconvex domains and bounded strongly pseudoconvex domains. Our…

A Sharp Lower Bound for the Spectrum of the Hodge Laplacian on Kähler Hyperbolic Manifolds and its Applications

Ye-Won Luke Cho, Young-Jun Choi, Kang-Hyurk Lee

In this paper, we establish a sharp lower bound for the spectrum of the Hodge Laplacian on Kähler hyperbolic manifolds. This bound is expressed explicitly in terms of the supremum…

On the Kähler-hyperbolicity of bounded symmetric domains

Young-Jun Choi, Kang-Hyurk Lee, Aeryeong Seo

In this paper, we characterize the Kähler-hyperbolicity length of a bounded symmetric domain, defined by its rank and genus, as a unique constant determined by a constant gradient…

A Kähler potential on the unit ball with constant differential norm

Kang-hyurk Lee, Aeryeong Seo

Let be the unit ball in and be the homogeneous Siegel domain of the second kind which is biholomorphic to . We show that the…

A characterization of the unit ball by a Kähler-Einstein potential

Young-Jun Choi, Kang-Hyurk Lee, Aeryeong Seo

We will show that a universal covering of a compact Kähler manifold with ample canonical bundle is the unit ball if it admits a global potential function of the Kähler-Einstein met…

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…
