DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MSR80/9/">Ha
 sse principle for simply connected groups</a>\nby Raman Parimala as part o
 f International Conference on Discrete groups\, Geometry and Arithmetic\n\
 n\nAbstract\nHasse principle for the isotropy of quadratic forms over numb
 er fields is the classical\ntheorem of Hasse-Minkowski. We describe Kneser
 's conjectures on Hasse principle for simply\nconnected groups over number
  fields and a conjecture of Serre in the general context of\ncohomological
  dimension 2 fields placing Kneser's conjecture in a very general context.
  We then\ndescribe questions and conjectures for function fields of curves
  over p-adic and number fields and\nsome progress in this direction.\n
