Fabrizio Andreatta - A p-adic criterion for good reduction of curves

Séminaire Paris Pékin Tokyo / Mardi 14 octobre 2014

abstract : Given a curve over a dvr of mixed characteristic 0-p with smooth generic fiber and with semistable reduction, I will present a criterion for good reduction in terms of the (unipotent) p-adic étale fundamental group of its generic fiber.
