Welcome to the website of Minseong Kwon (권민성; 權玟成).

I am a postdoctoral researcher at Morningside Center of Mathematics in Chinese Academy of Sciences. My research mentor is Baohua Fu (付保华).

I received my Ph.D. from KAIST in August 2025, under the supervision of Jun-Muk Hwang (황준묵). In September 2025, I worked as a postdoctral researcher at Gyeongsang National University, mentored by Kyeong-Dong Park (박경동).

My research focuses on Lie-theoretic methods in complex geometry and in algebraic geometry. Nowadays I am working on the following subjects:

complex contact geometry;
rational curves and their parameter spaces; and
spherical varieties.

Algebraic hyperbolicity of adjoint linear systems on spherical varieties

Minseong Kwon, and Haesong Seo

International Mathematics Research Notices, Mar 2026

Abs DOI arXiv

Moraga and Yeong conjectured that for a smooth complex projective variety X of dimension n, an ample line bundle A on X and an integer m ≥ 3n +1, very general elements of the adjoint linear system ∣ωX ⊗ A⊗m∣ are algebraically hyperbolic. We prove the conjecture for spherical varieties with smooth orbit closures. As a corollary, we conclude that the conjecture holds for horospherical varieties, and for toroidal spherical varieties. Furthermore, for any spherical variety, we show that the conjecture holds modulo the complement of an open dense orbit.

Classification of Equivariant Legendrian Embeddings of Rational Homogeneous Spaces into Nilpotent Orbits

Minseong Kwon

Mathematische Zeitschrift, Feb 2026

Abs DOI arXiv

For a complex semi-simple Lie algebra, every nilpotent orbit in its projectivization comes with a complex contact structure. For each nilpotent orbit, we classify projective Legendrian subvarieties that are homogeneous under the actions of their stabilizers in the adjoint group. In particular, we present a classification of equivariant Legendrian embeddings of rational homogeneous spaces into adjoint varieties.

Automorphism groups of toroidal horospherical varieties

Lorenzo Barban, DongSeon Hwang, and Minseong Kwon

Feb 2026

Abs arXiv

We establish a structure theorem for the connected automorphism groups of smooth complete toroidal horospherical varieties, that is, toric fibrations over rational homogeneous spaces. A key ingredient is an extension of the notion of Demazure roots from toric varieties to toroidal horospherical varieties. In particular, we provide a criterion for the reductivity of the connected automorphism groups of such varieties. As an application, we prove the K-unstability of certain P1-bundles over rational homogeneous spaces.
