Abstract
We consider the algebraic group GL1(A), where A is a division algebra of prime degree over a eld F , and the associated motive in the Voevodsky category of motivic complexes DM eff (F ). We relate the motive of GL1(A) to the motive of the Cech simplicial scheme X , associated to the Severi-Brauer variety of A, and compute the second dierential in the resulting spectral sequence for motivic cohomology.
