SUMMARY:Math Seminar Series
DESCRIPTION:
 Algebra\n
 \n
 Daniel Bragg, University of California, 
 Berkeley, will be speaking.\n
 \n
 The seminar 
 title is "Compactifications of supersingular 
 twistor spaces."\n
 \n
 Contact Rajesh S Kulkarni 
 (kulkar23@msu.edu) for more information.\n
 \n
 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.\n\n
