Le groupe SK_2 d'une algebre de biquaternions, by Baptiste Calmes

In this note, I give the main ideas of the proof of the exactness of a sequence relating the group SK_2 of a biquaternion algebra and the Galois cohomology of its center. It is the analogue of Rost's exact sequence for SK_1 of a biquaternion algebra.
