Description
In a suitable mixed characteristic setting, the moduli stack of flat vector connections can be endowed with a Frobenius-pullback operation. This talk is devoted to the properties of this map, which yields amongst other things a new construction of the $F$-isocrystal structure for rigid flat connections. This is joint work with Hélène Esnault.
