Alterations
Arbeitsgemeinschaft algebraische Geometrie WS08/09
An alteration is a proper map which is generically finite. De Jong
proved that every variety over a field can be covered with a smooth variety
by an alteration. This is a weak version of resolution of singularities that works also in characteristic p>0. For many applications this suffices.
We want to study the proof and possibly some of the applications.
Everybody is most welcome! The seminar will probably run in English.
Prerequisites: Algebraic Geometry (Schemes).
Date: Wednesdays 2-4 pm, room 403
