|Title||Equivalence relations for quadratic forms|
|Presenter||Detlev Hoffmann (TU Dortmund)|
|Author(s)||Prof Detlev Hoffmann|
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.
