Over perfect fields, the geometry of regular del Pezzo surfaces has been classified, but over imperfect fields, the problem remains largely open. ÌýWe construct the first examples of regular del Pezzo surfaces X that have positive irregularity h^1(X, O_XÌý) > 0. ÌýOur construction is by quotienting a regular, quasi-linear surface (i.e. a regular variety that is geometrically a non-reduced first-order neighborhood of a plane) by explicit rank 1 foliations. We also find a restriction on the integer pairs that are possible as the anti-canonical degreeÌýand irregularityÌýof such surfaces.
