Pure Anderson Motives and Abelian Sheaves over Finite Fields
Matthias Bornhofen, Urs Hartl
Pure t-motives were introduced by G. Anderson as higher dimensional generalizations of Drinfeld modules, and as the appropriate analogs of abelian varieties in the arithmetic of fu…
Change of Coefficients for Drinfeld Modules, Shtuka, and Abelian Sheaves
Urs Hartl, Markus Hendler
We study the passage from Drinfeld-A'-modules to Drinfeld-A-modules for a given finite flat inclusion A \subset A'. We show that this defines a morphism from the moduli space of Dr…
A Dictionary between Fontaine-Theory and its Analogue in Equal Characteristic
Urs Hartl
In this survey we explain the main ingredients and results of the analogue of Fontaine-Theory in equal positive characteristic which was recently developed by Genestier-Lafforgue a…
On a Conjecture of Rapoport and Zink
Urs Hartl
In their book Rapoport and Zink constructed rigid analytic period spaces for Fontaine's filtered isocrystals, and period morphisms from PEL moduli spaces of -divisible…
