Is there a Dieudonné theory for $p$-divisible groups (or for finite flat group schemes of $p$-power order) over *non-perfect* base-fields?



Dieudonné theory over non-perfect base fields
Johan de Jong sent me an e-mail with a reference to Jong, A.J. de. "Finite locally free group schemes in characteristic $p$ and Dieudonné modules" Inventiones mathematicae 114.1 (1993): 89-138. <https://eudml.org/doc/144143>.
