DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UAANTS/85/">
 p-torsion for p-covers</a>\nby Doug Ulmer (University of Arizona) as part 
 of University of Arizona Algebra and Number Theory Seminar\n\nLecture held
  in ENR2 S395.\n\nAbstract\nWe consider Z/pZ covers of curves in character
 istic p and the p-torsion group schemes of their Jacobians.  Such covers a
 re the building blocks of the towers Bryden Cais spoke about last week.  O
 ur aim is to understand the full Dieudonne structure\, not just the kernel
  of Frobenius.\n\nWe will give more details on groups schemes killed by p 
 and their Dieudonne modules\, introduce the Ekedahl-Oort stratification of
  Ag\, the moduli space of abelian varieties\, and state basic questions on
  how it interacts with the locus of Jacobians in Ag.  (This gives an intro
 duction to the AWS2024 courses of Karemaker and Pries.)  We end by stating
  a structural result on Dieudonne modules of p-covers and some of the rest
 rictions it places on group schemes.\n
