Categorical local Langlands and torsion classes of some Shimura varieties

Kieu Hieu Nguyen

We study the cohomology of various local Shimura varieties for . This provides an explicit description of the spectral action constructed by Fargues-Scholze in certain cases…

On categorical local langlands program for

Kieu Hieu Nguyen

We study various moduli spaces of local Shtukas in the setting of Fargues' program for . In certain cases, this gives us an explicit description of the spectral action which…

Compatibility of the Fargues--Scholze correspondence for unitary groups

Alexander Bertoloni Meli, Linus Hamann, Kieu Hieu Nguyen

We study unramified unitary and unitary similitude groups in an odd number of variables. Using work of the first and third named authors on the Kottwitz Conjecture for the similitu…

A Harder-Narasimhan stratification of the -Grassmannian

Kieu Hieu Nguyen, Eva Viehmann

We establish a Harder-Narasimhan formalism for modifications of -bundles on the Fargues-Fontaine curve. The semi-stable stratum of the associated stratification of the $B_{dR}^+…

The Kottwitz conjecture for unitary PEL-type Rapoport--Zink spaces

Alexander Bertoloni Meli, Kieu Hieu Nguyen

In this paper we study the cohomology of PEL-type Rapoport-Zink spaces associated to unramified unitary similitude groups over $\Q_p$ in an odd number of variables. We extend the r…

Shtukas adiques, modifications et applications

Kieu Hieu Nguyen

In this paper, via the study of the modifications of vector bundles on the Fargues-Fontaine curve, we prove a geometric formula relating the Lubin-Tate towers with the simple basic…

Un cas PEL de la conjecture de Kottwitz

Kieu Hieu Nguyen

The Kottwitz conjecture describes the cohomology of basic Rapoport-Zink spaces using local Langlands correspondences. In this paper, via geometrical studies of some Kottwitz-type S…
