The monodromy group of stratified bundles
Freitag, 4.7.14, 10:15-11:15, Raum 404, Eckerstr. 1
On a variety over a field of positive characteristic a stratified bundle is exactly what a flat connection is on a smooth manifold. Moreover, via the theory of Tannakian categories one can endow a stratified bundle with a monodromy group, in parallel with the complex case. We will see how this group varies in smooth families, proving a strong form of the positive equicharacteristic p-curvature theorem proposed by Esnault and Langer.
