Singular fibers of elliptic fibrations on normal surfaces
Taro Hayashi, Kazuki Utsumi
We study singular fibers of elliptic fibrations on normal \(K3\) surfaces. For a normal \(K3\) surface \(Y\) with minimal resolution \(ν\colon X \to Y\), we describe singular fiber…

Finite abelian groups of K3 surfaces with smooth quotient
Taro Hayashi
The quotient space of a surface by a finite group is an Enriques surface or a rational surface if it is smooth. Finite groups where the quotient space are Enriques surfaces ar…
