A note on the cohomology of moduli spaces of local shtukas

David Hansen, Christian Johansson

We study localized versions of the spectral action of Fargues--Scholze, using methods from higher algebra. As our main motivation and application, we deduce a formula for the cohom…

Moduli stacks of Galois representations and the $p$ -adic local Langlands correspondence for $GL_{2} (Q_{p})$

Christian Johansson, James Newton, Carl Wang-Erickson

We give a categorical formulation of the $p$ -adic local Langlands correspondence for $GL_{2} (Q_{p})$ ,as an embedding of the derived category of locally admissible rep…
