DESCRIPTION:Professor Raman Parimala\nThe classical invariants of quadrati
 c forms are the dimension\, discriminant\, Clifford invariant and the sign
 ature. These suffice to classify quadratic forms over number fields. Milno
 r's conjecture\, which was proved by Voevodsky\, proposes a sequence of su
 ccessive invariants for quadratic forms with values in Galois cohomology\,
  determining completely the form. We explain how this classification could
  be used to give bounds over a given field\, for the dimensions of quadrat
 ic forms with no nontrivial zeros.
