Automorphism groups of smooth cubic threefolds
Li Wei, Xun Yu
In this paper, we classify groups which faithfully act on smooth cubic threefolds. It turns out that there are exactly maximal ones and we describe them with explicit examples…
Hodge cohomology on blow-ups along subvarieties
Sheng Rao, Song Yang, Xiangdong Yang +1
We establish a blow-up formula for Hodge cohomology of locally free sheaves on smooth proper varieties over an algebraically closed field of positive characteristic. For this, we i…
Rational cubic fourfolds in Hassett divisors
Song Yang, Xun Yu
We prove that every Hassett's Noether-Lefschetz divisor of special cubic fourfolds contains a union of three codimension-two subvarieties, parametrizing rational cubic fourfolds, i…
Coble's question and complex dynamics of inertia groups on surfaces
Keiji Oguiso, Xun Yu
We study the inertia groups of some smooth rational curves on 2-elementary K3 surfaces and singular K3 surfaces from the view of topological entropy, with an application to a long…
