Home Research Teaching & Seminars Miscellaneous

I am interested in arithmetic geometry, in particular, in various forms of p-adic geometry. My primary research area is p-adic Hodge theory, namely Breuil-Kisin modules, prismatic cohomology and their applications. My other research interest is the topic of rational points on higher genus curves.

I am also interested in homological algebra, and its interaction with algebraic geometry.

Other notes

Čech complexes for crystalline cohomology [pdf] This note is a long-ish proof of the (also quite long) unproved Remark 07MM of the Stacks Project, about a variant of Čech complex that computes crystalline cohomology.

An example of ln-formally étale map that is not weakly étale. [pdf] This example came about as a part of a project that I participated in during the Arizona Winter School in March 2019. The project was associated with M. Morrow's lecture series "Topological Hochschild homology in arithmetic geometry". The project assistant was B. Antieau.

\pi-typical Witt vectors. [pdf] This note is a write-up of some basic properties of the (p-typical) Witt vectors construction adjusted to a uniformizer \pi of a local number field, with tediously elementary proofs. (No originality claimed.)[to be expanded]
