Abstract Bounded local G-shtukas are function field analogs for p-divisible groups with extra structure. We describe their deformations and moduli spaces. The latter are analogous to Rapoport–Zink spaces for p-divisible groups. The underlying schemes of these moduli spaces are affine Deligne–Lusztig varieties. For basic Newton polygons the closed Newton stratum in the universal deformation of a local G-shtuka is isomorphic to the completion of a corresponding affine Deligne–Lusztig variety in… 

Foliations and the cohomology of moduli spaces of bounded global G-shtukas

We decompose Newton strata in the special fiber of moduli spaces of global G-shtukas into a product of Rapoport-Zink spaces and Igusa varieties. This decomposition holds as well for associated adic

We give an overview of the theory of local G-shtukas and their moduli spaces that were introduced in joint work of U.~Hartl and the author, and in the past years studied by many people. We also

On the geometric connected components of moduli spaces of p-adic shtukas and local Shimura varieties

We study connected components of local Shimura varieties. Given local shtuka datum (G, b, μ), with G unramified over Qp and (b, μ) HN-irreducible, we determine π0(ShtG,b,[μ],∞×Cp) with its G(Qp)×

This is the first in a sequence of two articles investigating moduli stacks of global G-shtukas, which are function field analogs for Shimura varieties. Here G is a flat affine group scheme of finite

Functoriality of Moduli Spaces of Global $\mathbb G$-Shtukas

Moduli spaces of global $\mathbb G$-shtukas play a crucial role in the Langlands program for function fields. We analyze their functoriality properties following a change of the curve and a change of

THE GENERIC FIBRE OF MODULI SPACES OF BOUNDED LOCAL G-SHTUKAS

Moduli spaces of bounded local G-shtukas are a group-theoretic generalisation of the function field analogue of Rapoport and Zink’s moduli spaces of p-divisible groups. In this article we

Local Models For Moduli Spaces For Local P-Shtukas

In this article we study local properties of Rapoport-Zink spaces for local $\mathbb{P}$-shtukas by constructing local models for them. This provides a "local" complementary to the previous results
