    Rational syntomic cohomology of rigid spaces

    27 novembre 2025 - 14:00Salle de séminaires IRMA

    Starting with Drinfeld and Bhatt--Lurie’s construction of a stack computing prismatic cohomology, such stacky approaches to p-adic cohomology theories have received increasing attention in recent years. In this talk, I will describe a stack computing syntomic cohomology of rigid-analytic spaces with rational coefficients, mainly focusing the geometry of this stack and how it naturally sees various structures well-known in p-adic Hodge theory. Time permitting, I will also discuss an application to a conjecture of Clausen about analytic syntomic cohomology of C_p.
