| Jan 7, 2014 at 18:23 | comment | added | Jason Pioneer | Ok i understand this so far.But let me be bit more precise.For a 2 fold,anisotropic Pfister-quadric $X_\phi, \phi = <<a,b>>$ ,the motivic decomposition is $M(X_\phi) = M_\alpha \oplus M_\alpha[1]$. So this contains only one Motive up to twists. As far as i understand the situation,you are trying to tell me that for a n-fold,n>2 Pfister-quadric there will be completely different summands in the decomposition even modulo Tate-twists? This is what i mean. | |
