The Enriques surface of minimal entropy

Gebhard Martin, Giacomo Mezzedimi, Davide Cesare Veniani

Lehmer's number $λ_{10}$ is the smallest dynamical degree greater than $1$ that can occur for an automorphism of an algebraic surface. We show that $λ_{10}$ cannot be realized by a…

Enriques surfaces of zero entropy

Gebhard Martin, Giacomo Mezzedimi, Davide Cesare Veniani

We classify Enriques surfaces of zero entropy, or, equivalently, Enriques surfaces with a virtually abelian automorphism group.

Nodal Enriques surfaces are Reye congruences

Gebhard Martin, Giacomo Mezzedimi, Davide Cesare Veniani

We show that every classical Enriques surface containing a smooth rational curve is a Reye congruence.
