p-adic Borel extension for local Shimura varieties
Abhishek Oswal, Georgios Pappas
We show that the moduli spaces of Scholze's -adic shtukas with framing satisfy a -adic rigid analytic version of Borel's extension theorem. In particular, this holds for loca…
Integral models of Shimura varieties with parahoric level structure, II
Mark Kisin, Georgios Pappas, Rong Zhou
We construct integral models of Shimura varieties of abelian type with parahoric level structure over odd primes. These models are étale locally isomorphic to corresponding local m…
On the smooth locus of affine Schubert varieties
Georgios Pappas, Rong Zhou
We give a simple and uniform proof of a conjecture of Haines-Richarz characterizing the smooth locus of Schubert varieties in twisted affine Grassmannians. Our method is elementary…
Integrable branes in generalized -deformations
Georgios P. D. Pappas
We search for integrable boundary conditions and their geometric interpretation as -branes, in models constructed as generalized -deformations of products of group- and coset…
