Low codimension Fano–Enriques threefolds

In this paper we study Fano threefolds with a torsion divisor (Fano–Enriques). Due to this torsion divisor, they can be described as quotients of Fano threefolds by a finite abelian group action. We start from lists of Fano threefolds by Reid, Fletcher and Altınok and check which of them admit such...

Sumario:In this paper we study Fano threefolds with a torsion divisor (Fano–Enriques). Due to this torsion divisor, they can be described as quotients of Fano threefolds by a finite abelian group action. We start from lists of Fano threefolds by Reid, Fletcher and Altınok and check which of them admit such an action with a Fano–Enriques quotient.
