DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LNTS/176/">p
 -torsion Brauer classes in positive characteristic</a>\nby Domenico Vallon
 i (EPFL Lausanne) as part of London number theory seminar\n\nLecture held 
 in Imperial College London\, Room 139.\n\nAbstract\nIn this talk\, we will
  study p-torsion Brauer classes arising from differential forms in charact
 eristic p. We will then explain how such classes contribute to the Brauer
 –Manin obstruction. As an application\, we determine the Brauer–Manin 
 set of varieties that possess “many differential forms\,” and we obtai
 n new results on the Brauer–Manin set of supersingular K3 surfaces.\n
