Automorphisms of Frobenius twisted de Rham cohomology
Abstract
In this short paper, we prove that the moduli of automorphisms of Frobenius twisted de Rham cohomology functor is given by Gm. Our method is to use the notion of Gaperf-modules and its connection to the de Rham cohomology functor introduced in M22. As an application of the induced Gm-action, we reprove a result of Bhatt, Petrov, and Vologodsky on the decomposition of the Frobenius twisted de Rham complex.
