Cohomological invariants and R-triviality of adjoint classical groups
Cohomological invariants and R-triviality of adjoint classical groups
Using a cohomological obstruction, we construct examples of absolutely
simple adjoint classical groups of type 2An with n ? 3 mod4, Cn or 1Dn
with n ? 0 mod 4, which are not R-trivial hence not stably rational.

Abstract
Using a cohomological obstruction, we construct examples of absolutely
simple adjoint classical groups of type 2An with n ? 3 mod4, Cn or 1Dn
with n ? 0 mod 4, which are not R-trivial hence not stably rational.
