Sheared Witt Vectors
Bhargav Bhatt, Akhil Mathew, Vadim Vologodsky
V. Drinfeld and E. Lau introduced a ``decompletion'' of the ring of -typical Witt vectors, following earlier work of T. Zink. The goal of this paper is to offer an exposition of…
Prismatic -Gauges and Fontaine--Laffaille modules
Gleb Terentiuk, Vadim Vologodsky, Yujie Xu
Let be a perfect field of characteristic and its ring of Witt vectors. We construct an equivalence of categories between the full subcategory of the derived category…
Finding all solutions to the KZ equations in characteristic
Alexander Varchenko, Vadim Vologodsky
The KZ equations are differential equations satisfied by the correlation functions (on the Riemann sphere) of two-dimensional conformal field theories associated with an affine Lie…
On the weight zero motivic cohomology
Semen Molokov, Vadim Vologodsky
We prove that singular cohomology of the underlying space of Berkovich's analytification of a scheme locally of finite type over a trivially-valued field of characteristic…
