Dade's invariant conjecture for Steinberg's triality groups \(^3D_4(2^n)\) in defining characteristic. (Q2464506)

The authors prove that the Dade conjecture holds for Steinberg's simple triality groups \(^3D_4(2^n)\) in characteristic \(2\). As a consequence of this Uno's invariant conjecture is proved for \(^3D_4(2^n)\) in characteristic \(2\).
