Algebra

Daniel Bragg, University of California, Berkeley, will be speaking.

The seminar title is "Compactifications of supersingular twistor spaces."

Contact Rajesh S Kulkarni (kulkar23@msu.edu) for more information.

Supersingular twistor spaces are certain families of K3 surfaces over A^1 associated to a supersingular K3 surface. We will describe a geometric construction that produces families of K3 surfaces over P^1 which compactify supersingular twistor spaces. The key input is a construction relating Brauer classes of order p on a scheme of characteristic p to certain sheaves of twisted differential operators. We will give some results on the geometry of compactified supersingular twistor spaces, and some applications.
