On isomorphism numbers of "$F$-crystals"

Number Theory 2014-03-11 v1

Abstract

In this note, we show that for an ``FF-crystal" (the equal characteristic analogue of FF-crystals), its {\it isomorphism number} and its {\it level torsion} coincide. This confirms a conjure of Vasiu \cite{Va} in the equal characteristic case.
