Generalizations of Igusa surfaces
Pascal Fong, Matilde Maccan, Ludvig Modin
We give a criterion for the contracted product to have a singular Picard scheme, where is an elliptic curve, is a finite subgroup scheme, and i…

Isotrivial elliptic surfaces in positive characteristic
Pascal Fong, Matilde Maccan
We study relatively minimal surfaces equipped with a strongly isotrivial elliptic fibration in positive characteristic by means of the notion of equivariantly normal curves introdu…
