Abstract


We investigate equivalence relations for quadratic forms that can be
expressed in terms of algebro-geometric properties of their associated
quadrics, more precisely, birational, stably birational and motivic
equivalence, and isomorphism of quadrics. We provide some examples and
counterexamples and highlight some important open problems.
