W-translated Schubert divisors and transversal intersections
DongSeon Hwang, Hwayoung Lee, Jae-Hyouk Lee +1
We study the toric degeneration of Weyl group translated Schubert divisors of a partial flag variety of Lie type A via Gelfand-Cetlin polytopes. We propose a conjecture that Schube…
Kähler-Einstein metrics on smooth Fano symmetric varieties with Picard number one
Jae-Hyouk Lee, Kyeong-Dong Park, Sungmin Yoo
Symmetric varieties are normal equivarient open embeddings of symmetric homogeneous spaces, and they are interesting examples of spherical varieties. We prove that all smooth Fano…
Configuration of lines in del Pezzo surfaces with Gosset Polytopes
Jae-Hyouk Lee
In this article, we study the divisor classes of del Pezzo surfaces, which are written as the sum of distinct lines with fixed intersection according to the inscribed simplexes and…
Gosset Polytopes in Picard groups of del Pezzo Surfaces
Jae-Hyouk Lee
In this article, we research on the correspondences between the geometry of del Pezzo surfaces S_{r} and the geometry of Gosset polytopes (r-4)_{21}. We construct Gosset polytopes…
