Sixteen generators of the automorphism group of the Fermat quartic surface
JongHae Keum, Keiji Oguiso, Xun Yu
It has been a long standing open problem to find generators of the automorphism group of the complex Fermat quartic K3 surface; in fact, even an explicit number of generators has n…
Mori dream spaces and Q-homology quadrics
Paolo Cascini, Fabrizio Catanese, Yifan Chen +1
We show that Shavel type surfaces are fake quadrics of even type which are not Mori dream surfaces, yet there are infinitely many primes such that the reduction modulo is a…
Combinatorially minimal Mori dream surfaces of general type
JongHae Keum, Kyoung-Seog Lee
In this paper, we suggest a new approach to study minimal surfaces of general type with via their Cox rings, especially using the notion of combinatorially minimal Mori dre…
A surface birational to an Enriques surface with non-finitely generated automorphism group
JongHae Keum, Keiji Oguiso
We will show that there is a smooth complex projective surface, birational to some Enriques surface, such that the automorphism group is discrete but not finitely generated.
Examples of Mori dream surfaces of general type with
JongHae Keum, Kyoung-Seog Lee
In this paper we study effective, nef and semiample cones of minimal surfaces of general type with We provide examples of minimal surfaces of general type with $p_g=0, 2 \…
The bicanonical map of the Cartwright-Steger surface
JongHae Keum
We prove that the bicanonical map of the Cartwright-Steger surface is an embedding. We also discuss two minimal surfaces of general type, both covered by the Cartwright-Steger surf…
