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…
