On Automorphism Groups of (1,2)-Surfaces

Hang Zhao

Let $S$ be a minimal surface of general type with $K_{S}^{2} = 1$ and $p_{g} (S) = 2$ , called a $(1, 2)$ -surface. We give a geometric recovery and refinement of D. Wen's bound $|\mathrm{Aut}(S…

On open algebraic surfaces of general type whose log canonical maps composed of a pencil

Hang Zhao

Let $(S, D)$ be a minimal log pair of general type with $S$ a smooth projective surface and $D$ a simple normal corssing reduced divisor on $S$ . We assume that its log canonial line…

On the relative Morrison-Kawamata cone conjecture

Zhan Li, Hang Zhao

We relate the Morrison-Kawamata cone conjecture for Calabi-Yau fiber spaces to the existence of Shokurov polytopes. For K3 fibrations, the existence of (weak) fundamental domains f…

On numerically trivial automorphisms of threefolds of general type

Zhi Jiang, Wenfei Liu, Hang Zhao

In this paper, we prove that the group $Aut_{Q} (X)$ of numerically trivial automorphisms are uniformly bounded for smooth projective threefolds $X$ of general type…

Automorphisms of 3-folds of general type acting trivially on cohomology

Hang Zhao

Let $X$ be a minimal projective threefold of general type over $C$ with only Gorenstein quotient singularities, and let $Aut_{Q} (X)$ be the subgroup of a…
