Symbols, birational geometry, and computations

Brendan Hassett (Brown/ICERM), Jully 24, 2020.

We are interested in G-birational equivalence of varieties where G is a finite group. Kontsevich-Tschinkel and Kresch-Tschinkel have developed symbol formalism to construct invariants that show rich internal structure. We present examples of computations of these invariants for varieties in small dimensions, illustrating how they compare to existing classification techniques.
