Compact moduli of elliptic surfaces with a multiple fiber
Donggun Lee, Yongnam Lee
Motivated by Miranda and Ascher--Bejleri's works on compactifications of the moduli space of rational elliptic surfaces with a section, we study constructions and boundaries of com…

Positivity of the tangent bundle of rational surfaces with nef anticanonical divisor
Hosung Kim, Jeong-Seop Kim, Yongnam Lee
In this paper, we study the property of bigness of the tangent bundle of a smooth projective rational surface with nef anticanonical divisor. We first show that the tangent bundle…
