The Stochastic Schwarz lemma on Kähler Manifolds by Couplings and Its Applications

Myeongju Chae, Gunhee Cho, Maria Gordina +1

We first provide a stochastic formula for the Carathéodory distance in terms of general Markovian couplings and prove a comparison result between the Carathéodory distance and the…

Sub-Riemannian Geodesics on

Domenico D'Alessandro, Gunhee Cho

We explicitly describe the length minimizing geodesics for a sub-Riemannian structure of the elliptic type defined on . Our method uses a symmetry reduction whic…

Vanishing results from Lichnerowicz Laplacian on complete Kähler manifolds and applications

Gunhee Cho, Nguyen Thac Dung

In this paper, we show several rigidity results for harmonic -forms in complete Kähler manifolds. We also give several applications to study non-compact Kähler manifolds wit…

Rigidity results with curvature conditions from Lichnerowicz Laplacian and applications

Gunhee Cho, Nguyen Thac Dung, Tran Quang Huy

The Bochner technique is a classical tool in global differential geometry for proving vanishing and rigidity results by exploiting curvature conditions. Building on recent extensio…

Diameter theorems on Kähler and quaternionic Kähler manifolds under a positive lower curvature bound

Maria Gordina, Gunhee Cho

We define the orthogonal Bakry-Émery tensor as a generalization of the orthogonal Ricci curvature, and then study diameter theorems on Kähler and quaternionic Kähler manifolds unde…

Non-existence of complete Kähler metric of negatively pinched holomorphic sectional curvature

Gunhee Cho

We show the theorem which provides some sufficient condition to the non-existence of a complete Kähler--Einstein metric of negative scalar curvature whose holomorphic sectional cur…

Bergman metric on the symmetrized bidisc and its consequences

Gunhee Cho, Yuan Yuan

On the symmetrized bidisc G2 with the Bergman metric, the holomorphic sectional curvature is negatively pinched and the holomorphic bisectional curvature is not. The consequences i…

The Subelliptic Heat Kernel of the Octonionic Anti-De Sitter Fibration

Fabrice Baudoin, Gunhee Cho

In this note, we study the sub-Laplacian of the 15-dimensional octonionic anti-de Sitter space which is obtained by lifting with respect to the anti-de Sitter fibration the Laplaci…

The Kobayashi-Royden metric on punctured spheres

Gunhee Cho, Junqing Qian

This paper gives an explicit formula of the asymptotic expansion of the Kobayashi-Royden metric on the punctured sphere in terms of the expo…

The subelliptic heat kernel of the octonionic Hopf fibration

Fabrice Baudoin, Gunhee Cho

We study the sub-Laplacian of the -dimensional unit sphere which is obtained by lifting with respect to the Hopf fibration the Laplacian of the octonionic projective space. We…

Comparing the Carathéodory Pseudo-Distance and the Kähler-Einstein Distance on Complete Reinhardt Domains

Gunhee Cho

We show that on a certain class of bounded, complete Reinhardt domains in that enjoy a lot of symmetries, the Carathéodory pseudo-distance and the geodesic distance…
