In this talk, I will present a joint project with Stefan Schröer aimed at generalising Iskovskikh’s theorem, which describes minimal surfaces with vanishing irregularity and geometric genus. We focus on regular surfaces over imperfect fields and develop the theory of inseparable pencils, with particular emphasis on the case of characteristic 2.
