SUMMARY:Geometrically non-reduced varieties
DESCRIPTION:Speaker: Lena Ji\, Princeton University\n\nIn positive characteristic, there exist fibrations between smooth varieties where every fiber is singular or even non-reduced. In the latter case, the generic fiber of the fibration is geometrically non-reduced. We study the failure of generic smoothness and obtain a structural result about …
