周期Higgs-de Rham流的形变理论

Deformation theory of periodic Higgs-de Rham flows

Raju Krishnamoorthy, Jinbang Yang, Kang Zuo

摘要:

本文研究周期(对数)Higgs-de Rham流的形变理论。在适当的数值假设下,这等价于扭转(对数)Fontaine-Faltings模的变形理论。作为应用,我们给出了一个\emph{ordinarity}条件,它提供了一个$p^n$ -扭晶表示变形为$p^{n+1}$ -扭晶表示的充分条件.

英文摘要:

In this note we study the deformation theory of periodic (logarithmic) Higgs-de Rham flows. Under suitable numerical assumptions, this is equivalent to the deformation theory of torsion (logarithmic) Fontaine-Faltings modules. As an application, we formulate an \emph{ordinarity} condition, which provides a sufficient condition for a $p^n$-torsion crystalline representation to deform to a $p^{n+1}$-torsion crystalline representation.
