-integrability
Yujie Xu
In this short note, we prove the equivalence of Grothendieck-Katz -curvature Conjecture with Conjecture F in Ekedahl-Shepherd-Barron-Taylor. More precisely, we show that Conject…
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…
On the Hodge embedding for PEL type integral models of Shimura varieties
Yujie Xu
We give a simple proof that Kottwitz's PEL type integral models of Shimura varieties admit closed embeddings into Siegel integral models. We also show that Rapoport's and Kottwitz'…
Finiteness of fppf cohomology
Yujie Xu
Let be a Henselian DVR with finite residue field. Let be a finite type, flat -group scheme (not necessarily commutative) with smooth generic fiber. We show that $H^1_{\m…
