Derived and prismatic F-Zips (C03)

• Subject Area: Mathematics
• Term: since 2021

The project aims to study the total de Rham cohomology of proper syntomic morphisms in positive characteristic p > 0 and, more generally, over certain p-adically complete bases. The goal is to endow the total de Rham cohomology with additional structures extending those of an F-zip to obtain the notion of a derived F-zip. We want to study moduli spaces of derived F-zips to obtain mod p period spaces. These moduli spaces will be locally geometric derived stacks and we plan to study their structure and in particular their singularities. We also plan to study variants for log-syntomic morphisms. Using the pris¬matic cohomology we plan to extend these results in order to obtain mixed characteristic period spaces.
