The -rank stratification of the moduli space of double covers of a fixed elliptic curve
Kevin Chang, DuÅ¡an DragutinoviÄ, Steven R. Groen +3
In this paper we investigate the -rank stratification of the moduli space of curves of genus that admit a double cover to a fixed elliptic curve in characteristic .…

An unusual family of supersingular curves of genus five in characteristic two
DuÅ¡an DragutinoviÄ
We construct a family of smooth supersingular curves of genus in characteristic with several notable features: its dimension matches the expected dimension of any component…

Ekedahl-Oort types of stable curves
DuÅ¡an DragutinoviÄ
We extend Moonen's definition of Ekedahl-Oort types of smooth curves in terms of Hasse-Witt triples to all stable curves and show that it matches Ekedahl and van der Geer's definit…
