Q: Automorphisms of Frobenius liftings and degeneration of the Hodge-de Rham spectral sequence

The Thin WhistlerI am still studying Deligne and Illusie's paper (https://eudml.org/doc/143480), and I am again stuck, this time on pages 262/263. Assume $Y\longrightarrow S$ is a smooth morphism of $\mathbb{F}_{p}$-schemes, then $\operatorname{Lif}(Y,\tilde{S})$ is the gerbe of liftings to $\tilde{S}=S(\mathbb{Z...
