Free abelian group actions on projective fibered varieties

Sichen Li

Let $X$ be an $n$ -dimensional normal projective variety of Kodaira dimension $κ$ and $G$ an abelian subgroup of automorphisms such that all elements of $G\backslash \{\mathrm{id}\}…

Semiampleness on Jacobian elliptic surfaces of Kodaira dimension one

Antonio Laface, Sichen Li

Let $π : X \to P^{1}$ be a semistable Jacobian elliptic surface over $C$ , and set $χ = χ (O_{X}) \geq 3$ , so that $κ (X) = 1$ . Assume that the Mordell-Weil group of $π$ i…

Bounded cohomology property on Jacobian elliptic surfaces with simplicial Mori cones

Sichen Li

Let $X$ be a Jacobian elliptic surface with finite Mordell-Weil group and exactly one reducible fiber. We prove that if $χ (O_{X}) \geq ρ (X)$ , then the Mori cone of $X$ is simp…

Smooth projective surfaces with bounded cohomology property II

Sichen Li

Let $X$ be a smooth projective surface with Picard number two, where either $X$ is a geometrically ruled surface or the closed Mori cone is rational polyhedral. In this paper, we c…

Mori dream Jacobian elliptic surfaces of Kodaira dimension one

Antonio Laface, Sichen Li, Jihao Liu

Let $π : X \to P^{1}$ be a Jacobian elliptic surface over $C$ , and set $χ = χ (O_{X}) \geq 3$ , so that $κ (X) = 1$ . Assume that the Mordell--Weil group of $π$ is fini…

Integral Zariski decompositions on smooth projective surfaces II

Sichen Li

In this paper, we characterize three classes of smooth projective surfaces: relatively minimal elliptic surfaces with $χ \geq 1$ , rational surfaces $X$ satisfying that $- K_{X}$ iis nef…
