Foliations and the cohomology of moduli spaces of bounded global -shtukas
arXiv:1610.05935
Abstract
For arbitrary reductive groups defined over a finite field, we decompose Newton strata in the special fiber of moduli spaces of global -shtukas into a product of Rapoport-Zink spaces and Igusa varieties. This allows us to compare the -adic cohomology of these spaces together with the various actions on them.
