This is a survey article that advertises the idea that there should exist a theory of p-adic local analogues of Shimura varieties. Prime examples are the towers of rigid-analytic spaces defined by Rapoport-Zink spaces, and we also review their theory in the light of this idea. We also discuss conjectures on the l-adic cohomology of local Shimura varieties. 
The supersingular locus of unitary Shimura varieties with exotic good reduction
In this paper, we use a group-theoretic approach to give a concrete description of the geometric structure of the supersingular locus of unitary Shimura varieties with exotic good reduction. This
On the generic part of the cohomology of local and global Shimura varieties
Using the work of Fargues-Scholze, we prove a vanishing theorem for the generic unramified part of the cohomology of local Shimura varieties of general linear groups. This gives an alternative
Serre–Tate theory for Shimura varieties of Hodge type
We study the formal neighbourhood of a point in $\mu$-ordinary locus of an integral model of a Hodge type Shimura variety. We show that this formal neighbourhood has a structure of a shifted cascade.
ON THE SUPERCUSPIDAL COHOMOLOGY OF BASIC LOCAL SHIMURA VARIETIES
We prove that the supercuspidal cohomology of basic local Shimura varieties is concentrated in the middle degree, under a mild (and probably necessary) condition related to the local Langlands
Zelevinsky Duality on Basic Local Shimura Varieties
. We give a simple proof of a general result describing the action of the Zelevinsky involution on the cohomology of certain basic local Shimura varieties, using the machinery of Fargues-Scholze
Good and semi-stable reductions of Shimura varieties
We study variants of the local models constructed by the second author and Zhu and consider corresponding integral models of Shimura varieties of abelian type. We determine all cases of good, resp.
Eichler-Shimura relations for local Shimura varieties
In this note, we discuss several forms of the Eichler-Shimura relation for the compactly supported cohomology of local Shimura varieties, using the work of Fargues-Scholze.
Rapoport–Zink spaces for spinor groups
After the work of Kisin, there is a good theory of canonical integral models of Shimura varieties of Hodge type at primes of good reduction. The first part of this paper develops a theory of Hodge
Honda–Tate theory for Shimura varieties
A Shimura variety of Hodge type is a moduli space for abelian varieties equipped with a certain collection of Hodge cycles. We show that the Newton strata on such varieties are non-empty provided the
On the cohomology of Rapoport-Zink spaces of Hodge type
We prove the conjecture of Harris on the cohomology of Rapoport-Zink spaces for unramified reductive groups, under the "Hodge-Newton decomposibility" assumption. Our proof is based upon Mantovan's

Abstract. Consider a PEL-Shimura variety associated to a unitary group that splits over an unramified extension of $\Q_p$. Rapoport and Zink have defined a model of the Shimura variety over the ring

Under a mild condition, we prove that the action of the group of self-quasi-isogenies on the set of irreducible components of a Rapoport-Zink space has finite orbits. Our method allows both ramified
