New examples of cylindrical Fano fourfolds

Algebraic Geometry 2015-07-08 v1

Abstract

We construct new families of smooth Fano fourfolds with Picard rank 1, which contain cylinders, i.e., Zariski open subsets of form Z×A1Z\times A^1, where ZZ is a quasiprojective variety. The affine cones over such a fourfold admit effective GaG_a-actions. Similar constructions of cylindrical Fano threefolds and fourfolds were done previously in [KPZ11, KPZ14, PZ15].
