Two-Dimensional Torus Action on the Quadric Threefold and GW-DT-GV Correspondence

Kiryong Chung, Sanghyeon Lee

We compute Gromov--Witten (GW) and Donaldson-Thomas (DT) invariants (including descendant invariants) for local CY -folds over a smooth quadric threefold , up to degree .…

Hilbert schemes of low-degree rational curves on a prime Fano threefold of degree

Kiryong Chung, Dae-Won Lee

In this paper, we give a complete description of the Hilbert schemes of rational curves up to degree on a prime Fano threefold of degree . One of the key ingredients in…

DT-GV correspondence on the Mukai-Umemura variety

Kiryong Chung, Joonyeong Won

We compute Donaldson-Thomas(DT) invariants and their descendant invariants for the local Calabi-Yau 4-fold over the Mukai-Umemura variety via several localization formulas. Assumin…

Deformations of the tangent bundle of a projective hypersurface

Insong Choe, Kiryong Chung, Jun-Muk Hwang

For a nonsingular hypersurface of degree , we show that the space $H^1(X, \End(T_X))$ of infinitesimal deformations of the tangent bun…

Conics in quintic del Pezzo varieties

Kiryong Chung, Sanghyeon Lee

The smooth quintic del Pezzo variety is well-known to be obtained as a linear sections of the Grassmannian variety under the Plücker embedding into $\mathbb{…

Rational curves in a quadric threefold via an -representation

Kiryong Chung, Sukmoon Huh, Sang-Bum Yoo

In this paper, we regard the smooth quadric threefold as Lagrangian Grassmannian and search for fixed rational curves of low degree in with respect to a torus actio…
