Abstract: 
Let G be a split semisimple algebraic group over a field and let A be an oriented cohomology theory in the sense of Levine-Morel. We provide a uniform approach to the A-motives of geometrically cellular smooth projective G-varieties based on the Hopf algebra structure of A(G). Using this approach we provide various applications to the structure of motives of twisted flag varieties. The talk is based on a joint work with Victor Petrov.
