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.

Bounding geometrically integral del Pezzo surfaces

Fabio Bernasconi, Gebhard Martin

We prove several boundedness statements for geometrically integral normal del Pezzo surfaces over arbitrary fields. We give an explicit sharp bound on the irregularity if i…

Automorphisms of del Pezzo surfaces in odd characteristic

Igor Dolgachev, Gebhard Martin

We complete the classification of automorphism groups of del Pezzo surfaces over algebraically closed fields of odd positive characteristic.
