Geometry of 3-dimensional del Pezzo fibrations in positive characteristic
arXiv:2412.12090
Abstract
We survey some of the recent works on the geometry of del Pezzo surfaces over imperfect fields, with applications to 3-dimensional del Pezzo fibrations in positive characteristic. We place particular emphasis on cases where the general fibres of the fibrations are not smooth
